Dlc Not Showing In Shop On Tsw2 (pc)

A little while ago I downloaded TSW2 from Epic Games when it was free, Only recently Installed it but for some reason no DLC is showing in the shop, Is this a bug with TSW2 or is it because I got the game for free?

Thanks in advance.

Edit: Turns out I have it installed via xbox game pass but when looking on xbox app no DLC shows there either.

 

You should be able to see them on the TSW 2 page on Epic store. Just scroll down.

 

well I did this and as soon as I loaded the epic games store I quickly realised that I have it installed via xbox game pass not epic games, Not sure how I manged that one but thank you for your help chacal, no to update the post.
