How to change left Chevy C2 2008 retrovisor

Good morning, I would like to know if anyone knows how the rearview mirror is disassembled on the left side of a Chevy C2, recently a motorized my car hit and the mirror was loose, I suppose something is broken, ask how much it would change it and it is charged at least here in my country, I think it is something that I can do a weekend if I get the information about how to disassemble it, I hope you can help me.
