Open browser to display BPMN from JavaFX

I have a JavaFX application (not web) and a BPMN. All I want to do is if the user clicks a button in my application, the browser opens and displays the BPMN (just like demo.bpmn.io). Editing is not necessary. Any ideas?

Someone already did that (see this topic).

Does that help?

Yes, thank you. Thank helped.
