My iPhone 13 mini is frozen and won’t respond when I try to do things.

My iPhone 13 mini won’t respond when I try to do things, restart or anything.

I have tried all the guides on how to force it to restart and I don’t know how to get it to function at all. It has frozen completely and I’m trying to make it loose all battery. I can’t call anyone since the phone has all the information I’d need to contact anyone. The screen keeps blinking like crazy.

I’ve kept my old phone so that I can write here, please help me?
