Running P14s G5 closed for a long time

External keyboard, mouse, display. I am considering running the laptop closed and in a vertical stand like this (no product link, this is not spam https://m.media-amazon.com/images/I/61355VLREaL._AC_SL1500_.jpg). Would this be bad for cooling, I wonder.

I could keep the laptop 180 degrees open like a poster on the wall but then all the force is on the bottom thin edge of the machine, that worries me.
