Lazy Search Music repo missing?

I have installed LMS 7.9 in a Docker container on my QNAP server, and have everything running properly. The only thing that I couldn't restore is the Lazy Search plugin. The repo at https://github.com/hickinbottoms/squ...aster/repo.xml doesn't seem to work. I can download the .zip of the last archive from github, but I can't figure out how to install this .zip without going through the repository.

Does anyone know how to do this?

Thanks!
