What is the best way to read the chat on Steam?

I plan to do my first live stream soon. However, it will be the case that my camera is only filming me and I'm not sitting in front of my PC. But now I would like to have the opportunity to read the chat and also write it in. The cell phone is actually too small for me. And my laptop is at the desk because OBS is running on it and the camera is connected. To be honest, I don't want to buy an expensive tablet for that reason.

Then buy a cheap tablet.

You can switch over
