Can Auth0 integrate with Microsoft PowerApps?

I’m trying to set up a custom connector in PowerApps using the Generic Oauth 2 provider, but I cannot seem to get it to work correctly. I’m guessing it just some setting somewhere, that is wrong.

I have created a Auth0 application as a SPA pointing to the API in question and tried to set the PowerApps connector

I’ve taken the values from the endpoint tab from Auth0 application configuration under the Advanced Settings section. I’ve also set the redirect URI in the Auth0 configuration, and when I test it gets to the login page and I can enter credentials, but after that I get an error. My best guess is that it is not redirecting correctly, but I think I have set that correctly. Any ideas what I might be doing wrong? Is this integration even possible?
