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?
