BPMN.IO in angular app : toolbox not rendred

Hello,

I’m trying to add bpmn editor to my angular app.
I’m using this code snippet to do it

import * as BpmnJS from 'bpmn-js/dist/bpmn-modeler.production.min.js';
ngOnInit(): void {
    this.modeler = new BpmnJS({
      container: '#canvas',
      width: '100%',
      height: '600px',
      propertiesPanel: {
        
      },
      additionalModules: [
        
      ]
    });

    this.modeler.createDiagram(); // or ..importDiagram(xml);

but I can’t see toolbox and no edition capabilities are added.
BPMN diagram are correctly drawn.

What should I do to add bpmn editor to my angular component.
Thanks.
