Can't create my own annotations?

I am very new to Jalview (taking a bioinformatics course in my grad program and have never done this before). I am trying to get PFAM domains to show up on my MSA. I was able to use a database to figure out where the domains are and make features and groups out of them on my alignment. However, that is as far as I could get. I can't seem to figure out how to make my own annotation on my Macbook OR my PC. All the suggestions I saw said to right click on the annotation rows, but when I do that nothing pops up. Is there another way to add your own annotation without having to use the auto-calculated annotations? Thanks!
