Please enable a warning prompt before closing Microsoft TEAMS. I keep clicking on the 'x' in the upper, right corner to close a window thinking that it will close the file or page I'm currently looking at within Microsoft TEAMS. It is actually the close application button and immediately closes Microsoft TEAMS entirely! There is no warning prompt that comes up that asks 'Do you want to exit the program?'. I have to keep logging in and logging in and logging in, because I am naturally attuned to closing a page within the application using the 'x'. Please enable a warning prompt and if one exists already, please make it easy to toggle on and off. I've looked everywhere in options and settings and cannot find a way to turn one on.
