Can't use Windows Popups to answer calls

[MaFa]

We're receiving calls, but I'm not able to use the Windows Popups to answer them. Just nothing happens, when I click on it.
As I found in other threads, this may be due to the fact that the app runs in elevated mode.

How do i turn elevated mode off?
I can't find a way to do that. I installed 3CX from Microsoft Store and it immediately starts elevated.

Whenever I found information on this topic, someone says that you have to switch to non-elevated, but it's no where described how to actually change that.

You’re saying you get a UAC prompt when running the Store app?

None of the clients need elevation.

no, we don't get the prompt.
It just starts with windows in autostart and is elevated
