Not able to prevent deleting some particular nodes using keyboard delete in drawflow used in an Angular Project.

I need to prevent deleting my start and end nodes, so I changed the visibility of cross button. But user is able to delete it using Delete button in keyboard.

I have gone through issues #98 but couldn't get an idea of what exactly I need to do. Please help.

Please review this comment. It's about overriding the delete function. Implement your logic.

Yeah, this helped. Thank you. I was putting the code after editor.start() earlier that's why it was not working.
