My Xbox profile would not present all my video games…

Why is it that my pals' xbox profiles present the video games they purchased from different shops, akin to Purple Useless Redemption 2 (rockstar launcher) or Ranibow Six Siege (steam), however they don't present them on mine. My account is linked to steam. Any answer???
