How to mirror hole?

Newbie here!
I have a hole that I wish to "mirror", but I cannot select the hole to mirror. It looks like the hole has been merged into the main "part" so I can only mirror the part, not the hole.
Can anyone explain what I am doing wrong? (It's a simple shape so I can easily replicate the hole, but I am keen to understand more, for more complicated builds!). Here's the link, the hole is obvous, and I want it mirrored to the other side of the main part:

Any help much appreciated, thank you! 😀

Common problem. Change "Part mirror" to "Feature mirror."
