A pointer has suddenly shown up on my phone and won't go away (Xiaomi)

I've never posted on Reddit or anything so please don't kill me if I have flagged this post wrong or whatever, also, bad English warning.

So, I was just screen recording a game on my phone (Xiaomi) and I have a setting for which when Im screen recording it shows a pointer on my screen, so it shows where Im tapping on my phone. While I was screen recording my phone crashed and the screen went black, it happens sometimes so I just clicked reset (I think that's the name in English?) and waited for it to turn back on. When it turned on, it still showed the pointer. I've tried to look up on Google how to turn it off through the settings and nothing worked, what can I do?

I know this may sound stupid as Im not very good with technology, I can barely turn on a computer, but, please, any advice on how to resolve this are appreciated
