AEM 6.5.12: Not able to add annotations and comments on a page for a read-only author

Hey all,

I am currently on AEM 6.5.12. We are looking into annotations and comments for a specific use case where an author with read-only permissions on a page should be able to add annotations and comments. However, I get an error when I try to add the annotations and comments on a page as a read-only user.

ERROR: Annotation create operation failed. Similar error for comments.

Is this by design? Couldn't find anything in the docs.

Thanks!
