MakeCode Raspberry Pi Shutdown? - help


I am a teachers that has been using MakeCode arcade with my STEM classes since beta. We have finally decided to make a physical arcade and followed the tutorials using a Raspberry Pi Zero. Everything works great, but how do you safely shut it down?

The plug ended up getting pulled and then we got a warning about proper shutdown on the next boot up. Is their a simple solution or a guide that can help shut it down the safe and proper way?

Thank you
