What happens when a custom item field has no roles under the 'Access' tab. What is the default behavior?

AI generated answer (using internal Slack threads):

When a custom item field has no roles under the 'Access' tab, the default behavior is that the field will not be visible to any roles. This is because the 'Access' tab in the custom field setup determines which roles have permission to view or edit the field. If no roles are specified, then the field is effectively hidden from all users, regardless of their role. If you want to display the custom field but not allow users to add records from it, you need to set the access to the record that is being listed to 'View'. This will allow the field to be visible, but users will not see the plus button to add new records. This setting is done at the role level. Remember, the access level of the custom field and the access level of the record being listed in the field are two separate settings. The former controls whether the field is visible or editable, while the latter controls whether users can add new records from the field. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
