this is probably a dumb question, but how do I update?

I tried to update to Catalina through the App Store. It did not work and I'm just wondering if there is some other way

First you need to update Clover Bootloader,

Then Kexts (Whatevergreen, Lilu etc).

Then the Catalina, Try to update using 10.15.7 Combo update.
