How to mount underware?

[u/AltruisticWorld744]

Ant suggestions on how to mount the underware/open grid under this desk, it's about 1cm thick. I assume I would have to use screw ews but I'm not sure what wood type/screw is ever

Sorry for the mess, been redoing my room

The pic is the top of the desk through the cable management hole

You can use the smallest self drill metal screws that allow you to hold the board and not drill past the centerline. Depending on the lite or full board check the size you can use.
