How to add element template to custom bower bpmn js project ?

we are trying to add element template into below custom bower project using code from here https://forum.bpmn.io/t/element-templates-usage-in-property-panel/809/3 we could not achieve element template with this documentation. If we can get some detail help on this issue it would be great ?

index.js

`var BpmnViewer = require('bpmn-js/lib/Modeler');
var camundaModdleDescriptor = require('camunda-bpmn-moddle/resources/camunda');
var additionalModules = [
  require('bpmn-js-properties-panel'),

  // 1. require camunda provider instead of the bpmn one (!)
  require('bpmn-js-properties-panel/lib/provider/camunda')
];
BpmnViewer.prototype._modules = BpmnViewer.prototype._modules.concat(additionalModules);
// 2. include camunda moddle descriptor
BpmnViewer.prototype._moddleExtensions = { camunda: camundaModdleDescriptor }
module.exports = BpmnViewer;`

You cannot use element templates with the BpmnViewer (it is a diagram viewer). Use the BpmnModeler instead.

If you got more questions, please open a respective topic in the bpmn.io forum.
