Safe to mount 32" TV directly into insulation without beam?

So I have been across the wall and back several times with a magnet in the corner where we want to mount this TV. It does not seem to stick anywhere that would suggest there is a beam we could mount to. I took some blank faceplates off dry wall boxes and I can feel there is a stud in a perfect position, but it is back 3/4…

So I have been across the wall and back several times with a magnet in the corner where we want to mount this TV. It does not seem to stick anywhere that would suggest there is a beam we could mount to. I took some blank faceplates off dry wall boxes and I can feel there is a stud in a perfect position, but it is back 3/4 inches from the plaster.

We have these things, not sure what they are called, you screw them into plasterboard and then you can put a screw into them. They are supposed to hold 15kg each. They only go in about 1 inch. I could fit 6 of them into the arm wall mount.

The TV weights 5.kg, and the arm probably less than 2kg. Behind the plasterboard is hard Kingspan insulation. Would it be safe to mount the arm only into the plaster and insulation? Should I try to pick some sort bolts or very long screws tomorrow that will be long enough to mount the arm through the slab, several inches of insulation, and then into the beam? I had thought behind the slab there would be beams between the insulation, but like I said I have only found a beam in this spot several inches behind the insulation.
