Left click on laptop broke in half

Jan 20, 2019
The title explains all, my left click didn't break software wise. But the actual button broke in half, I can't really show a picture because this forum is to hard to use. I'm using an MSI laptop model GE72-2QF. I'm not sure what to do at this point I really don't want to buy a mouse, so how can I get someone or myself to get a new button and attache it on to there. Any suggestions?
