feature request: redirect back to invites after logging in

[ghost]

What do you want to see?

My use case is Revolt as a discord alternative for a chat app, but the official Revolt is blocked. I want to have every user who signs up on my instance join my Revolt server on that instance. How could I do that, either by manually joining users to my server for them or by giving them an invite link?
The latter would be nice, but when Revolt detects no logged-in account on that device, it asks them to sign up/log in. However, I want to take this one step further by reshowing the invite link once they have logged in automatically. Thank you and I am amazed at Revolt!
