Glass print bed question

I purchased a creality glass printing bed and cant seem to get it working correctly. My issue is that the ender base blate has two screws protruding and any other build plate comes with 2 v’s cut to allow snug fit with no front overhang. New to the 3d printing do please be gentle…

Just remove the screws of the back and thats it:

Disregard the failed print haha. I upgraded to a PEI bed sheet and never went back to glass bed or any other.
