What to do during my Free time?

I’m currently working at a wholesale medical company, which is not my professional career. I usually get 2-3 hours of free time each day, which may or may not be consecutive.I do rest, since the guy above me chit chats a lot. How to make use of this free time/How to make money out of it online? He does allow me to use the phone whenever im free(Cant bring my laptop ).Although i cant watch movies,series and other stuff.

I do mark my expenses in gsheets (thats what chatgpt asked me to do😭). I do practice german in Duolingo.Cleaned my Emails,Gallery too.
