Battlefront DLC showing installed but not working

Question, I have battlefront on disk, downloaded outer rim from xbox store, it shows that it's installed but isn't showing up anywhere so we can play it.

Hello there!

Have you tried seeing if its been installed? DLC may download but not always install automatically

So find Battlefront in Games and Apps and then click the Menu button on the controller and click Manage Game, then if you look down the page it should have a Ready To Install section. The DLC should be there, just click on it to start the installation

Hope this helps, post again if it doesn't solve the issue

Ok... thanks. I will try that. All I can do is sign out of my account, but I don’t know how to actually remove it from the Xbox. How do you do that?

To remove your account, please select System > Settings > account > remove accounts and then select your account and select Remove to confirm then re-add your account.

In this case I would recommend reinstalling the game as well as removing your account. If this doesn't fix the issue, I would suggest getting in touch with the game developer.
