Handle private pages

[hectorsector]

In our early testing, we learned that private pages don't work well, we get the error:

HttpError: Resource not accessible by integration

We should look into whether it's possible to expand this action to tackle private pages. If not, we should reflect that in the lab instructions.

we should reflect that in the lab instructions.

This is now reflected in the lab instructions via 4ccd959, so this doesn't need to be immediately resolved.

@hectorsector I ran into this yet again yesterday. As it stands right now, I don't think there is anything we can do on our side of things to fix this. The API has to change to allow integrations (actions) to work with private pages.
