Add new shape(Rest Service Task) to Camunda Modeler Pallet

I want to customize the Camunda Modeler by adding the new task(custom element) to the pallet. Need to add new shape to Camunda Modeler Pallet,and it should act as a rest service task when I drag and drop it. Could you please provide me the steps to do this as I am new to this kind of work.

Hi @jyothsna.c
I would suggest you review the following example of custom palette elements - GitHub - bpmn-io/bpmn-js-example-custom-controls: An example how to add custom editor controls to bpmn-js as a first step
