An electrician has installed a dry lining box for a cat6 network terminal. These boxes are supposed to have a metal insert inside each of the yellow parts, which accepts the type of screw that is standard for attaching UK electrical switches, sockets etc. Unfortunately, both of these metal inserts are missing, so there is no obvious way to attach the faceplate.
I don't want to replace the entire box as the plasterboard has already been tiled.
What alternative methods could be used to attach the faceplate securely?
Somebody asked about removing the yellow inserts from these boxes on Screwfix, and Appleby responded that "in design principle and as a general rule these [yellow parts] should never be removed as the lugs themselves cannot be replaced." I hope somebody here can be more helpful than this.
Again, this is being used for networking — not mains — so electrical safety is not a serious concern.

There are lots of easy ways to do this.
Very popular old method, toothpicks. Insert a couple toothpicks in those holes and snap them off flush. If you don't have toothpicks, just shave a few chips off a pencil or something.
Steel wool - pack the holes with steel wool, the screws will hold well enough for light non critical duty.
Drill the hole out so that a small concrete or drywall anchor will fit in there.
Use a larger screw, enlarge the holes on the faceplate if necessary.
You get the idea, just get creative, just about anything will work if you let it.
