Handsome Edition Question

Hello.

Last Friday, I bought the Handsome Edition for XBOX One from a local game shop. They said that the DLC was not included, which is fine, because I've already played it on PC, and for 20€ it isn't a bad deal.

I just wanted to know if there is any way of getting the DLC's for any of the games. It's not urgent or anything, I just wanted to have the full game.

Thanks, and have a good day
