Can't Install borderlands 4 on steam deck?

Not sure what is going on but tried to install but it say "available on windows"? It wont install at all and I have tried even in desktop mode. I cant remember if I bought it through my steam deck or through my phone (should it not matter either way?) so not sure if I just wait til tommarow when the game is released everywhere or is there a fix to this. Hoping for some answer cause I wanna play later today when I get off from work.
