Hi
It’s quite a hard process and I don’t recommend doing it
I would see the screen and buy a new one
But here’s how to do it if you want to do it
This video is for iPhones but is the same process

You have to carefully cut through thick adhesive between the display and the glass without breaking the display
Hopefully this helps
Any questions please ask
Thanks:-)
