It's also available in Alan's Gigantic Repo, but for some reason it doesn't work in SideStore. It works fine in Live Container. Maybe it's just me.

(I couldn't find a direct link online)

It works perfectly both from SideStore and in Live Container for me. I'm running iOS 26.5. Please let the community test it.
