You can’t add this app here

This usually happens because of incorrect permissions.

In order to add the app successfully one of the following needs to be true:

  • You are an administrator of the site collection of the site where you are installing the app.
  • You are a tenant administrator.
  • You have an app catalog setup to handle installation requests.

The reason for this is that the app needs to be trusted when added because of its permission requirements.
