Recommended attachments for Alex Drawers?

[DankDoodles]

I got a new desk (made out of a Kitchen Dutch blocks) and got Alex drawers.

Problem is that I don't want the desk to start sliding around. What should I attach the Alex drawers to the desk with to prevent it moving?

 

I was thinking of using an L-shaped metal bracket to attach the two but I am not completely sure. Any ideas?

It could even be flat and attach on the sides if the table is thick enough, that way you wouldn't have the bracket on top of the desk.  Another option might be some double-sided mounting tape? I'm not sure if that would cause issues with wobbliness if it's too thick. Perhaps even take out the top drawer and use screws to go into both the top of the cabinet and into the table?
