[admin scope issue][media]

[fe51]

Hi there,

As a user with admin scope, I have encountered the following issue :

I have been denied access on a route where I am supposed to have access rights

Indeed, I get a error 403 using the get route : /media/{media_id}/url and the following msg :

{
  "detail": "This access can't read resources from group_id=3"
}

I am available to provide further information if required, Thanks a lot :)
