Stop resizing or moving the window without my consent! Just leave it alone!

Zoom resizes my window whenever I join or leave a breakout room, goes fulls-screen when someone shares content, constantly moves things around without my consent. There should be a setting that "locks" the window, so that it behaves like almost every other application, behaves properly and normally, simply stays where I have put it. In fact, that should be the default behaviour. Why is this difficult? If I, the user, put the application in full-screen, maximized, or restored, it should stay in that state until I, the user, tell you differently. It is not for the developers to impose on me how I want and need to arrange my desktop, without my consent.
