If you need outside help with your migration project, the Migration assessment is an excellent way for them to quickly scope your environments.
Access is shared through an Assessor role you can grant in Microsoft 365.
You can either create an unlicensed user account in your Microsoft 365 tenant to grant that role or grant it to an external user who must go through a few extra steps to sign in.
