Is it fine to put my Pocophone F1 on bag while it auto play games?

[Big Boar]

hello people I play online games but sometimes I need to put my phone inside my bag during work or party. is fine to put it on bag while it auto play? the pocophone has liquid cooling system so I assume it is for a short time. It only stayed for around 40 mins and it just warmed. It not damaged isn't it?
