This is a plugin used on the Västerås Chess Club Website to publish news in the discord server whenever a news post is posted on the website. Only those with a specific role on the server will receive a notification. The plugin should work for other websites using WordPress too.
With this plugin an admin can set a discord webhook in Settings->General. He can also set a discord role, so those with that role gets a notification on discord.
You can see how to create a webhook on the discord server here: https://www.geeksforgeeks.org/websites-apps/how-to-make-a-webhook-in-discord/
When setting Discord role, you need to use the Id of that role. This can be accessed by right clicking on a role in discord and copy Role ID.
