How can I open the power menu in Android without pressing the power button?

The power button on my Android phone is dodgy and doesn't always work. I think it's on its last legs so I want to avoid pressing it if possible to extend its lifespan! I know nothing about coding or how Android works. But I was wondering if it is possible to send the button press event to the system using this sort of code somehow: KeyEvent#KEYCODE_POWER . Is there a way I can open the power menu via the screen only? Is there something I can type into a terminal (how do you get a terminal in Android?) that would open the power menu?
