Galaxy NG access to private EE

Hello!
I’m using Galaxy NG and uploaded an Execution Environment to it. After that, I made it private via an API request with "private": true. I’d like to grant access to specific users to download it, but I haven’t figured out how to do that.
I found the container.containerdistribution_consumer role and assigned it to a user, but it allows downloading from any private repositories, not just the specific one. I tried adding this role to the user in the Access EE tab, but I get the error: The role does not contain any permission for that object. The same error occurs when I add this role to the group associated with the EE.
How can I resolve this issue and enable specific users to download private EEs?
