ppc_assign_exceptions() and blocking anonymous users from a specific post

Hello,

I am working with PublishPress Permissions and I’m trying to use the ppc_assign_exceptions() API.

My goal is to block read access to a specific post for anonymous (logged-out) users only, while keeping access unchanged for all other users and groups.

I have reviewed the documentation for ppc_assign_exceptions(), but I am not sure what is the correct way to target the anonymous/logged-out user group.

Specifically, I would like to know:

1. Is there a built-in metagroup for anonymous or logged-out users?
2. Is wp_anon the correct metagroup ID to use?
3. What is the recommended way to assign a read exclusion for a single post to anonymous users only using the API and the function ppc_assign_exceptions()?

My objective is:

• Post ID: 3416
• Anonymous/logged-out users: cannot view the post
• Logged-in users: no change
• Existing permissions for other groups: no change

Thank you very much for your help.
