Requesting a connector from Discover
A member asks from Customize → Connectors → Discover for a missing connector (Ask an admin), with an optional reason of up to 500 characters.
The admin sees it in Organization → Connectors, in the N pending requests block (with the Connector requests switch, Approve and Dismiss), and in Notifications → Requests, with the count, the date and the reasons. Approving turns the connector on and emails whoever asked; when the connector is on by any path, the requests close on their own and the requester gets the email with the link to Discover.
