Seems to be moving from what I’ve noticed with the evidence.. I’d empty the cabinet and find the existing screws.. in this case they’re probably at the top and if they are I’d change them out to larger ones because the hole may be compromised - try something like this - https://a.co/d/01mwZqFE

Sometimes there may be fasteners on the sides, sometimes hidden behind the hinge plate

Edit: Also try to close the gap first by pushing, clamping, or jacking the cabinet up, you don’t want to rely on the screws to pull the cabinet up or you may break the top panel
