How do I fix up the cracked corner of my monitor bezel?

[flat jewel]

It just broke off somehow, I was hoping to fix it with glue, but the piece bounced into a different dimension after falling and hitting my desk, never to be found again. I will not be able to not see it.

If you lost the piece, you don't

You could always fill the gap with something and then use a little marker/paint or smth but that might end up being even more noticeable
