Trigger business process (client side) from button

Hi community,

I try to trigger a business process from a custom button. I in the post that I need the ProcessModuleUtilities to achieve that. Here is my code :

define("MTF_Candidat1Page", ["MultiChoiceMixin", "ProcessModuleUtilities"], function(ProcessModuleUtilities) { 
	return {
		entitySchemaName: "MTF_Candidat",
		...
		methods: {
			OnClickCreateInterview: function(){
				var args = {
					sysProcessName: "MTFtestbtn" // this is the name of my business process. It simply send me a mail for now.
				};
				ProcessModuleUtilities.executeProcess(args);
 
				this.showInformationDialog("Busniess process triggered"); // just to show something to let me know the function triggered properly the busniess process
			},
		},
		...
		diff: /**SCHEMA_DIFF*/[
				...
				{
				"operation": "insert",
				"name": "BtnCreateInterview",
				"values": {
					"layout": {
						"colSpan": 24,
						"rowSpan": 1,
						"column": 0,
						"row": 7
					},
					"itemType": 5,
					"classes": {
						"textClass": [
							"actions-button-margin-right"
						],
						"wrapperClass": [
							"actions-button-margin-right"
						]
					},
					"click": {
						"bindTo": "OnClickCreateInterview"
					},
					"tag": "OnClickCreateInterview",
					"caption": {
						"bindTo": "Resources.Strings.BtnCreateInterviewCaption"
					},
					"hint": {
						"bindTo": "Resources.Strings.BtnCreateInterviewHint"
					}
				},
				"parentName": "ProfileContainer",
				"propertyName": "items",
				"index": 7
			}
			...
		]/**SCHEMA_DIFF*/
}

Now when I click on the button on my candidate page I have this error :

"Uncaught TypeError: ProcessModuleUtilities is undefined"

Do you have other docs to trigger business processes on custom button press ?

Best regards,

Julien
