Anyway, my answer: yes. I have a profile on XBox, Switch, and Google Play Games. I connect with friends on all the platforms. I share achievements and activities and screenshots and sometimes chat.

In my book "ActivityPub: Programming for the Social Web", I talk about federating gaming platforms. I think you should be able to connect to an account on Steam from your XBox (or Mastodon) account. Add them to your friends list, and follow their activities.
