Hello there[url=https://cdn.discordapp.com/attachments/902560216871239752/989591085506515074/Hellothere.gif],[/url] While Bungie created the content, the individual platforms (Steam, Xbox console, Xbox PC, Epic, PlayStation) each control the licenses that are needed to access and play the content on their respective platforms. This is beyond Bungie's control. If you would like to see Steam accept your Xbox console License, you would need to petition Valve/Steam to do so.
