Installed DLC from Legendary CLI, but the game can not detect the DLC

I was playing Borderlands 2 and I saw that I can add the free UHD pack, so looked around a bit and found out that Heroic uses Legendary as backend, so we can just use legendary to add the DLC. But here I am, after downloading the UHD pack but when launching the game from Heroic, Borderlands 2 fails to detect the DLC UHD pack.

Is there a way to update some flag or something in order to make the game detect the DLC?
