https://api.us.nylas.com/v3/workspaces/auto-groupAuto-group grants
Starts a background job that sorts grants into workspaces by email domain, depending on the filters set. The job considers only grants that aren't in a workspace yet. If you don't set any filters, Nylas considers all unassigned grants in the application.
If no workspace exists for a grant's domain, the job creates one with auto_group set to true
and a generated name.
