Teams guest invitation process

Wanted to give a more deeper perspective on this problem based on the recent behavior observed.

The invite redemption email seems to be similar between the ones sent through graph api and through the Teams desktop app (while adding the guest through the manage team->add member dialog). However the behavior is different when the url in the email is clicked as seen below:

Teams APP: The user is taken through the following process:

- Email Verification (via verification code)
- Microsoft account creation & verification (via verification code)
- Automatic linking of microsoft account to Teams account

Graph API: Here the steps are slightly different

- Email verification
- Microsoft Account creation
- Teams account creation - this is an extra step when redeeming the url from the API. Here the guest is forced to create a new Teams account with a new organization. Eventually when you end up creating a team account, you end up in your own organization than the one you were invited to.

Has anyone seen this behavior?
