My mistake, I was under the impression you had not installed it yet. I thought you had perceived its absence in the Chaotic repo as an obstacle to getting it installed.
I did not intend to discourage you from requesting it to be added. I honestly have no idea if this package would be appropriate to add or not. It's really not up to me either way. If you feel it would be a benefit if it were added, go ahead and add the request as an issue on the GitHub page or on this thread: Everything about Chaotic-AUR packages
If you decide to just keep it as an AUR package, do yourself a favor and set up /etc/garuda/garuda-update/config with UPDATE_AUR=1 so your AUR packages get automatically updated with the rest of your system (as described here: Garuda Update | Garuda Linux wiki). One less thing you have to worry about!
