Premium Edition Soundtrack - Way to Download Music Files?

[Cosmosis]

I pre-ordered the Premium Edition for XBOX Series X and received my code and cool swag yesterday in the steelbook.  However, I cannot find a way to actually *download* the soundtrack.  Is the special "app" truly the only way to experience the soundtrack and artbook?  On my TV?  Or am I missing a step somewhere? (I tried installing the soundtrack/artbook to my PC using the XBOX app, but when I tried launching it was told it was not authorized for that device.)

Same request here. I also just realized the tracks seem integrated in the app (XBOX/PC) and had hoped to have them in my soundtrack library in my car (USB) where I have PoE sound tracks as well. Hope this can be done for those who purchased the premium edition.
