To give guest users access to a custom object, CK can use guest user organization-wide defaults (OWD). OWD are a feature that allows you to set the default level of access that guest users have to records of a custom object. You can use OWD to grant Read Only or Read/Write access to guest users for a custom object. For example, CK can use OWD to give guest users Read Only access to the VolunteeringEvent object.

The members that will be able to see the Rich Content Editor component are those that are part of both the New York City audience and the Legal Department audience. Audience targeting is a feature that allows you to display pages and components to certain users based on their assigned audience. An audience is a group of users who share common attributes, such as profile, location, or language. When you assign an audience to a page or a component, only the users who belong to that audience can see it. If you assign multiple audiences to a page or a component, only the users who belong to all of those audiences can see it.
