To share the Flow Deliveries page, click on the share button in the top right corner of the Deliveries list page. Only a SUPER_ADMIN or an org ADMIN can create a token by clicking on the share button. Once a token has been created, anyone can share the Deliveries page.
The public Deliveries page will show all deliveries, associated with a specific Flow. You can still click the button to view the Drilldown for a specific Delivery.
It will not display the sidebar or the breadcrumbs.
