Feature Request | Role Claim and Role assignment for Oauth2

[itzteajay-glitch]

Firstly I want to say thank you for this awesome plugin it's done wonders for my little site!

I currently leverage authentik for my authentication provider and I was hoping that role claim could be implemented in the application. In another application I use it's implemented fairly well so I'll include screenshots of their UI to help provide some context.

This would be incredibly useful as it would provide me the ability to manage all roles in my wordpress site from my provider and therefore leverage roles in my provider across all my various services.
