How to have apps open maximised while stage manager is active?

I love stage manager but don't like the extra space it uses up. So I usually maximise my windows so that I can just see stage manager only when hovering to the left edge of my screen.

I want to be able to have apps fully maximized when I open them up, so that stage manager doesn't take up space. Is this possible and if so, how do I do it?

Thank you so much in advance
