I'm trying to add Thunderbird to the top panel. Chrome, VLC, etc., all add very well. But Thunderbird doesn't appear anywhere on the list of apps for which I can create a launcher. I was surprised to click on the Menu icon and not find Thunderbird anywhere in any of the categories of apps!

Why doesn't it appear anywhere except on the panel at the bottom of the screen? Thanks.
