Iphone 13 literally stop working rn.

Hey, I stopped using my phone for 15 min and left him on my bed. After this my iphone literally stopped working. I cant use any app, off screen, call, message anything literally dead. I can just watch the screen and my battery.

I am trying to contact support but no one can contact me. Any ideas? How to turn off the phone?

(Restart buttons and siri didnt work)
