I think it'd probably follow a similar format to either the basketball or the football.
As for qualification: I think it'd be like basketball where the teams that do the best at the World Cup get regional spots, then there is a qualifier. So, with a hypothetical field of 12 teams, 8 of which qualify via regions (2 Asia, 2 Australasia, 1 everywhere else), a hypothetical 2022 Olympics would have had: and, uhhhhh, I guess automatically make it. WI would be a bit of an issue, tbh, but that could be figured out.
Then a four team qualifying tournament - I suspect would make, and then maybe :irl: etc
With You could have it that IF they qualify, there could be a qualifying tournament between the WI nations to take that spot.
