I was only able to find one refrigerator with a tray underneath the bin and I wasn't able to locate anything in the service manual.
What I saw was that there are two screws on the left side but those are for the door flap. The screws on the right side seem to be for a large plastic piece that looks to have hinges on the left side. I felt underneath the tray for the bin and noticed two notches about 3-4" apart.
My best guess is that you remove the two screws and the large plastic piece is removed by pulling on the right side, then once you remove the large plastic piece, there should be two screws on the inside that hold the tray for the bin. Please note that this is conjecture.
I would recommend reaching out to a certified technician to replace these trays. When was the unit purchased?
