What application you have to publish your launcher, I just implemented a project on Android with public applications, and inhouse and they were published correctly, make sure you do several things.
First log in to PLay / work with your account that you registered to enroll the EMM, validate in your managed applications and export them to apps and books in your console.
Once there you assign them to your desired groups (smartgroups) and two then assign them in the laucher and the launcher assign it to the same smartGroup from the previous point, I hope it serves you, happy afternoon.
