Added async receiver using Azure Client Side Library. So It will listen queue in continues mode.
You need to pass parameters in JavaScript
event parameter should be a client action with one input parameter which will be used to receive message from service bus queue.
example : "$actions.Refresh(`${messageReceived.body}`)"
note : do not change parameter name of Refresh client action
Client Action Refresh which will be used as input for JavaScript and will receive message from service bus queue
