Ok i was thinking when the emtire avengers army assemble in the climax of Endgame. I understand how all of them were contacted and made aware of what was happening. Except the Wasp. She was snapped out of existance on multi story carpark. How did wong or dr strange contact her as neither would have been aware of her.

The avengers that were snapped in wakanda made sense as dr strang would have contacted wong who wpuld have contacted them. Same with the asgardians. But Wasp was by herself just doesnt make sense
