IntelliJ IDEA Plugin for BPMN designer

Question

I've found this post about BPMN files designer, I tried to open designer window in every way, but i can only open diagram preview. Did anyone use jBPM plugin and can tell me how can I open designer window?

Edit

For simplicity, i'm using this bpmn file:

<?xml version="1.0" encoding="UTF-8"?>
 
<definitions id="definitions"
xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"
targetNamespace="http://www.activiti.org/bpmn2.0">
 
  <process id="helloWorld">
 
    <startEvent id="start" />
    <sequenceFlow id="flow1" sourceRef="start" targetRef="script" />
    <scriptTask id="script" name="HelloWorld" scriptFormat="groovy">
      <script>
        System.out.println("Hello world")
      </script>
    </scriptTask>
    <sequenceFlow id="flow2" sourceRef="script" targetRef="theEnd" />
    <endEvent id="theEnd" />
 
</process>
 
</definitions>
