Using Favorites in Android app



My Favorites list in the Android app is not the same as my Favorites list in the web version. That’s ok (it could even be great), but now I need to know how I can add a tag or a project to my favorites in the Asana-app for Android.
It all works fine in the web version, but in the Android version I just can’t find how to ‘star’ a tag or project to make it visible in the Favorites list.
Thanks for your help!
