OAuth2 provider with anonymous login

[archont94]

I'd like to create OAuth2 provider in Authentik, which will support both logged in Authentik users and guests (who don't have account/tokens etc).

I know that this sounds weird, but basically I'd like to return different token content based on scopes provided in POST request as a hacky way to add feature to my app, as I'm using OAuth2 anyway. I just need to allow guests access for app, but for some endpoints I would verify this magic value from token. I tried to add anonymous authentication flow, but it doesn't work, I'm just not able to get token with CURL if I will not provide any way of auth (user+pass or secret token). Is there a way to achieve that?
