How to manually reset a Lenovo Android tablet?

I've forgotten what the passcode is to my Lenovo tablet - I can't remember what model it is either - and I'm trying to factory reset it. I can access the tablet with facial recognition, but when I go into settings and try to factory reset it, it tells me that it requires my passcode D:
I've tried:
Volume up + power
Volume down + power
Volume up + volume down + power
Is there a certain order that I have to press them in?
