Question about Actiforce Cable tray Swing black

I have this table Ultradesk MOMENTUM the top is 1.8cm thick so I couldn't use longer screws I mounted the tray with 2 screws each left and right the middle one didn't work because there was a recess. My table is not solid wood but should still hold several kilos, right?

I have approx. 5-10kg cable + 10-way connector strip from Brennstuhl inside...
holds perfectly, but I used other (longer) screws than the ones included.
-->With a solid wood table, the enclosed screws should also be sufficient...
it is recommended that two people assemble the table... (at least if you don't want to/can't turn the table upside down)
-can also be done alone- but then it is a bit fiddly)
