PC Tsw2 Dlc In Tsw3?

I have bought tsw2 from epic games, and also a couple of dlc. I was wondering, if I could use those dlc with tsw3, if I would buy it from steam. In other words, do the epic games tsw2 dlc work on the steam tsw3?
Thanks.

 

You're buying a license for the Epic games version, so won't work if you then buy TSW3 from steam

 

Steam to steam. Epic to epic.

 

And MS Store to MS Store. << these licenses work on both PC and XBox.

 

Thanks, I will buy tsw3 from epic then!
