Included Features

• Tabs
• Device Permissions (geolocation, media)

Interaction with app - Desktop View

Interaction with app - Mobile View

Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app package (.zip file link below) to your teams and/or as a personal app. (Uploading must be enabled for your tenant, see steps here).

Tab Device Permission: Manifest

Prerequisites

To test locally, NodeJS must be installed on your development machine (version 16.14.2 or higher).

```bash
# determine node version
node --version
```

• dev tunnel or ngrok or equivalent tunneling solution If you are using Ngrok to test locally, you'll need Ngrok installed on your development machine. Make sure you've downloaded and installed Ngrok on your local machine. ngrok will tunnel requests from the Internet to your local computer and terminate the SSL connection from Teams.

• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

• Microsoft 365 Agents Toolkit for VS Code or TeamsFx CLI

Run the app (Using Microsoft 365 Agents Toolkit for Visual Studio Code)

The simplest way to run this sample in Teams is to use Microsoft 365 Agents Toolkit for Visual Studio Code.

1. Ensure you have downloaded and installed Visual Studio Code
2. Install the Microsoft 365 Agents Toolkit extension
3. Select File > Open Folder in VS Code and choose this samples directory from the repo
4. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps
5. Select Debug > Start Debugging or F5 to run the app in a Teams web client.
6. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (uploading), Microsoft 365 Agents Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

Setup

NOTE: The free ngrok plan will generate a new URL every time you run it, which requires you to update your Azure AD registration, the Teams app manifest, and the project configuration. A paid account with a permanent ngrok URL is recommended.

1. App Registration

Register your application with Azure AD

1. Register a new application in the Microsoft Entra ID – App Registrations portal.
2. Select New Registration and on the register an application page, set following values:
   • Set name to your app name.
   • Choose the supported account types (any account type will work)
   • Leave Redirect URI empty.
   • Choose Register.
3. On the overview page, copy and save the Application (client) ID, Directory (tenant) ID. You'll need those later when updating your Teams application manifest and in the appsettings.json.
4. Navigate to API Permissions, and make sure to add the follow permissions:
   • Select Add a permission
   • Select Microsoft Graph -> Delegated permissions.
   • User.Read (enabled by default)
   • Click on Add permissions. Please make sure to grant the admin consent for the required permissions.

2. Setup NGROK

3. Run ngrok - point to port 3000

   ngrok http 3000 --host-header="localhost:3000"

   Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

   devtunnel host -p 3000 --allow-anonymous

3. Setup for code

• Clone the repository

  git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

• In a terminal, navigate to samples/tab-device-permissions/nodejs

• Install modules

  npm install

• Start the bot

  npm start

4. Setup Manifest for Teams

• This step is specific to Teams.
  • Edit the manifest.json contained in the ./appManifest folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
  • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
  • Zip up the contents of the appManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)

Running the sample - Desktop View

• Install the App in Teams Meeting
