Shares the workflow with members of your organization and stops sharing it with others, in one call. Sharing a workflow gives edit access, and it appears in their workflow list.

Only the workflow's owner and org admins can do this. People in add who already have it, and the owner, are reported in data.skipped; people in remove who did not have it are ignored. Read the current list from Get Workflow Overview (shared_users).

A refusal changes nothing; its code says why, and emails lists any refused addresses.
