A stopgap plugin that clarifies why leaderboards on custom songs are not supported and allows the user to download one.
Currently only ScoreSaber and BeatLeader are supported, but if any other Beat Saber leaderboard services want to be included while this is used as a solution feel free to PR.
This repo uses code from LeaderboardCore and is thus licensed under GPL3. Other parts of the codebase have contributions from MIT-licensed sources BeatSaverSharper and ModAssistant, and will have an additional license at the top of the file to reflect this.
