Accent marks on Mac

I’m trying to figure out how to enter accent marks in Anki Desktop on my Mac. I tried following the instructions here, but the referenced keyboard is not actually there.

It seems these instructions in the docs aren’t up-to-date. Does anyone have any ideas? If I were just trying to create cards, I would find another way. But I want to use input on my cards, so I need to be able to enter the accent marks in foreign words while I’m studying. Thanks!

You can add it with the plus button. It’s shown grey in the following screenshot because I have already added it on my system.
