bugs behind glass on 2019 Mac

I've seen a couple of posts on here but they were quite old so thought I would ask again.

Over the last week 4 x small thunder bugs have somehow made their way behind the glass of my 27" 2019 iMac and have died.

If I am correct unlike my previous older model, the glass cannot be removed on the newer model.

Is there in fact a way to remove it the glass, or is there anything I can do?

The bugs are not loose enough to move if I shake or tap the screen, and I have tried vacuuming back through the vents and memory slots without success.

The Mac is just over a year old so 4 black spots on the screen regardless of what they are has really ****** me off...
