How would I create an "Exhale" sound in MS4?

I am currently in the process of trying to, by ear, transcribe the song "Avalon" by Keiki Kobayashi, from the game Ace Combat Zero: The Belkan War.
Throughout this song, there's an instrument (very likely computer-generated) that sounds like somebody exhaling, but with high reverb. It sounds incredible in the original song, but I can't even BEGIN to think of what instrument in the MuseScore/MuseSound libraries would be able to imitate it.
For context and so y'all can hear it for yourselves, here's the song (start at 0:40): https://www.youtube.com/watch?v=IIGN_Rl4Tyc
How would I best replicate this sound in MuseScore 4? Because I'd hate to just relegate it to a cymbal of some kind.
