Is your feature request related to a problem?

At the moment when new users who don't have a Postman Account join a team via SSO, they would expect the username in Postman to be the one they use for SSO.

Right now we randomly generate the username for these users automatically and they are not prompted like other new Postman users to create a username. The must do this afterwards in their profile/account settings.

There is currently an opportunity is to enter a name but it is blank by default (not taken from AAD SSO).

This flow can be a bit confusing for new users/orgs onboarding

Describe the solution you'd like

Prompt for username creation for new users signing up in SSO or maybe a modal that we generated a username and they can change it in settings.

Describe alternatives you've considered

No response

Additional context

Creating external feedback so users can track progress.
