Hi @Sam Teddy ,
Well, I think I might know what the problem you're describing is. When opening a modal window in Edge, the title bar will display this content, which is related to the account you are currently logged into, and this behavior is by design. Something like this(logged as presonal account):
So in modal window state, I‘m afraid that you cannot hide it. But if you don't want to show them, you have to show them as a tab instead of a modal window.
