How to redirect users from invite signup to an external URL

Support
1

Is there a way to redirect users to an external URL from the invite sign up.

The idea is something like :

Discourse Invite Signup → Tally Form → Discourse Post Redirect using Tally

2

Also, I have created a page using landing page plug-in but the invite link after sign up could not even redirect to it.

3

So something like:

Discourse Invite Sign up → discourse/landingpagecustomlink.com

Would that be possible anyhow?

Is it possible to add an external URL to the Invite Re-redirect page and allowing Sign Up using Google, Facebook, or others too?
