Hi,
Thanks for contacting us here about this extension.
1. Media access control for multiple authors, each will see their own media folder only.
2. Each author can get their own media from their Google photo connection.
3. Each author can get their own media from their Instagram connection.
1. Yes, you can restrict users to access Media library by Role or User roles.
Then they can upload and see their media in their folders. For more details:
