Whats the iControl REST API command to get FWR overlapping status

The TMSH to get the FWR overlapping status is

 

tmsh show security firewall policy myPolicyName rules overlapping-status

 

Whats the iControl REST API equivalent ? I tried the following but it does not work.

it gives

 

{ "code": 404, "message": "Object not found - overlapping-status", "errorStack": [], "apiError": 1 }
