OAuth2 webhooks

[cohen2804]

I implemented a WEBHOOK to add a claim to a JWT token.
The flow works, but I need to add a claim based on a value from the client.
How can I get a value from the client to the WEBHOOK payload (maybe inside extra)?
I tried to add a URL parameter to the authURL and to the exchange, but it isn't being received by the WEBHOOK.
I am developing with Go.

@cohen2804 Did you actually find a workaround for your use case? If not, I think my pr might address this use case if it gets approved #3790 .
