Allow users to copy selections between multiple editor channels and vice versa

Summary

Allow copying of selections between editors that are open across operating system on different or same channels. User needs to be able to open a model on any channel, select a part of the model (BPMN, DMN) and copy the selection to other editor he uses. It can be desktop, VSCode or other VSCode tab that is open, Online editor or other online editor, github PR edit etc.
The selection is a XML (string) so this should be possible, the idea is same as if I am using text editors and copying text from a webpage.

Goals

Allow user to copy selections of models (BPMN, DMN) across different editors open on same OS.
