Playoffs Fixtures

Hey does anyone have a link or can explain to me how do the #1 seeded teams get to 'pick' their opponent? I've seen a lot of stuff on Twitter about who wants to pick who.

How does it work? What if 2 teams want the same team?

i think the pick order is random

they will have a draw to see which team gets first pick and so on and then they will pick, the next person will have to pick from the remaining
(I think)

also when is the whole ‘picking thing’ happening, will it be live?
