What it is

Sets up device to be managed by EMM (Enterprise Mobility Management), which "allows organizations to securely enable employee use of mobile devices".

Might also be what does the actual management on your device, if you set it up as a work device.

Commands

adb shell pm uninstall --user 0 com.google.android.apps.work.oobconfig

To put it back:

adb shell cmd package install-existing com.google.android.apps.work.oobconfig

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
