Hello, everyone! I recently just got an under desk drawer (Flexispot S01) to help with desk clutter. I, however, failed to account for all of the crossbars under my desk making it difficult for me to position the drawer where I want to. My current game plan right now is to attach a wooden under desk spacer to hopefully clear the crossbars but being a total noob, I have zero clues and ideas on how to go about it. The ones I need to adjust for are the diagonal crossbar off in the front corner and the vertical bar as the mount directly lines up with it. Any and all suggestions will be appreciated :)

P. S. The only woodworking/carpentry experience I have is from my 6th grade wood shop class so I have loads to learn still.
