Meta Avatar - Failed Entitlement check 7 - user doesn't have app in library

H all,

I made a side-loading build of an oculus app with meta avatar feature in Unity. 
I am able to load and see my avatar, but the other users that are part of my organization can't.
They got that message "Failed Entitlement check 7 - user doesn't have app in library".
Is there any solution? 

Thanks in advance.
