Migration Manager for AD Windows 10 Machine domain Move - Modern Apps

Can anyone offering anything around what happens to Modern Apps (downloadload from Microsoft store) when the machine and user account are migrated from Source (where the apps were originally downloaded) to the Target.
Will the apps need to be downloaded again?
What impact could there be to them in terms of the machine now being a member of new domain?
the user account is now from the new Domain, so is the app tied to the source identity?
