I just noticed on my Edge browser, I have two different profiles (work and personal). on 1 profile, I have a one-click interface (fill, copy UN, copy Pwd, copy 2fa code. On the other profile, I have two click interface as you described.

So do this: go to setting (lower right coner) -> appearance -> set width to extra wide, check compact mode, check show quick actions.

that should do it.
