Hello people!, I just finished a run for a game called DESPOSIS it's a new game (it was released 2 months ago tho) but I can't find it, you guys know what I'm missing?

Have you seen it on Speedrun.com at all? Speedrun.com doesn't have every game, and won't add every game; depends on how big the speedrunning community for it is. If you want to, you can request it be added (https://www.speedrun.com/support/tickets/new) but expect a delay and maybe even refusal.

Oh srry peekobo0 it's my first time doing speedrun and been here, gonna try doing a request, thank you
