Jupiter spy mission navigation help

[PastorButtNut]

As of today the elusive acolytes have returned with their fantastic mods, however when I had gone to AMALTHEA, the jupiter spy mission, to hunt down Angst she had spawned where we tenno spawn. That being up the massive wind tunnel that everyone falls down. A player in the squad had said there is a way to get back up there by simply walking over and standing on top of the grates that is pushing the air upwards and double jump. However no matter how much I tried I couldn't get up there, is there something I'm missing here? I'd like to know how to get back up should a similar situation occur as I was unable to get the mod that Angst dropped however that one player that told me how to get up there did; so obviously there is in fact a way. Any tips are appreciated!

Thanks!
