Rest AP related IRule

I was able to add iRule. Now trying to attach that rule to Listener but getting error, Trying using this page: https://clouddocs.f5.com/cli/tmsh-reference/v13/modules/gtm/gtm_listener.html

Tried different ways but no success so far, Let me know what is wrong with my request:

1) First attempt:  

{"name":"listener1.example.com","rules": {"name":"ruleTest"},"address":"<mylistenerIp>","sourceAddressTranslation": {"type":"automap"},"translateAddress":"enabled","translatePort":"enabled","enabled":true}

Error:

{"code":400,"message":"Found unexpected json pair at property /gtm/listener/~Common~listener1.example.com/rules. The json pair is \"name\":\"ecsRuleTest\".","errorStack":[],"apiError":1}
