Option to See a Pop-Up Window when Receiving Calls

I would like an option to see a pop-up window when receiving calls, as we do on Skype. There we can simply click a button to answer the call, whereas on Discord we must first click the small tray icon to open Discord, and click an answer button there.

We can even lose calls because of the extra hassle required to answer them. At least it would be good if clicking the desktop notification for calls would open the Discord window or answer the call.
