Disney Infinity 3.0 for Xbox 360 on Xbox one?

I wanted to ask if I would buy the Disney Infinity 3.0 Starter Kit for the Xbox 360 now, could I play it on an Xbox one?

If it's listed in the compatible games catalog, it definitely is, and the game is listed, so have fun

Could you tell me if it's in the catalog because I don't know how to look at it and I'm stupid for that

Is about to be read on the Xbox site, search for Xbox downward compatibility on Google

Does this also work with the disk and the portal of the xbox360?

Must, otherwise it's pointless
