I know everything you said but they needed Pim particles to get small enough to use the portal.
Didnt Captain America take a handful of them joints when they went back to that SHIELD bunker? that was more than enough to get them back and to the present and what looked like a few extra bottles
--Edit--
Nah maybe not.. Wouldn't explain how Nebula got back AND how Thanos could shrink the ship... lol iono bruh
