Longest game ever?

I did remember some very long games, but in any official Riot Championship, what was the longest match?

longest match/series or longest map? cause then the bo5s would be the longest if it’s the longest series

i think it was tsm vs genG there was a lot of overtime

M3c vs FNatic it was like 21-23 2h+ match

Forze vs fpx second map
(Idk how to link a map sorry)
