Copy/paste elements from model to model


I used keyboard: { bindTo: document} in modeler constructor and it works well within the model, but I would like to be able to bring elements from one model to another by just copy/paste.

I tired to implement this GitHub - nikku/bpmn-js-copy-paste-example: An example how to copy and paste between multiple instances of bpmn-js
but I can’t put element in clipboard and access it from model opened in another tab.

Any assistance is appreciated, thanks.
