Trying to use Oauth 2.0 "Request Token" with email magic link authentication

I’m trying to use Postman’s OAuth 2.0 “Request Token” feature with Monzo’s API, however I hit a dead-end in the authenticate window because Monzo uses an email magic link which redirects back to the token exchange callback URL. (As opposed to redirecting within the original browser window like a traditional OAuth 2.0 password auth form would do).

Is there any magic postman:// app deep link callback URL I could possibly use to make this work?

Hi there,

Welcome to Postman community!

Can you please try this call back URL

When I try this, the magic link in my email opens a new browser tab with the URL above. I get a HTTP 200 response with headers but no body:

The Postman app OAuth modal stays open on this screen (nothing happens):
