Anonymize users on a group by ImportManager class

This script is for anonymizing all users of a group by Import Manager class (set user info such as user email, name, phone number, address to empty). Please input your groupResourceId.

number groupResourceId = ;
if (Group_isMemberOfGroup(User_getLoggedInUser().ResourceId, groupResourceId)) print("You are member of the group, the script cannot continue");

	array importData;
	array a = User_getUsersByGroupResourceId (groupResourceId);
	if(a.Count == 0) print("The group has no user");
	else{

		for(j for 0; 9)//9 user phonenumber types
			data.Add("#ERASE");
