jellyfin has one too and are currently in the process of getting into the official LG app store, awesome!
it was rejected a couple of times for some bugs the LG reviewers found, all of which are fixable and being worked on. looks pretty much a done deal.
Unfortunately, it's been pretty quiet the last few months after seemingly getting close to a retry in the LG store.
