Game Bar doesn't work

So I made a new Microsoft account for the halo master chief collection. I don’t actually remember the email I used for the master chief collection but my username is InspiringSpoon. I bought it off of steam. There’s no way for me to see who’s added me, because the Xbox game bar “feature” (its not a feature its a hindrance and a abomination to game design) does not work for whatever reason. Wow -Yoinking!- perfect.
