The administrative user has the ability to configure which metadata fields are included to be viewable by default when sharing collections.
This can be done from the Media Manager UI. Navigate to ‘Settings’ (1) → ‘General settings’ (2) → ‘Collections’ (3).
Now click in the field ‘Add fields’ under ‘Metadata shown for shares’ section and select metadata fields from the dropdown list.
The triple dot symbol next to each individual metadata field gives access to more options: ability to remove it.
Click ‘Save’ to confirm the changes or ‘Cancel’ to discard them.
