Capture click of a control or element

[lehno]

What problem does this feature solve?

I created a few custom plugins to show formated data in the editor. I would like to click on it and invoke an external function to open a popup or something else

What does the proposed API look like?

When adding a control, be able to send a function as a click callback or be able to listen to mouse click event and check if click has element with control extension

    document.addEventListener('click', (evt) => {
      const positionContext = this.editor.command.getPositionContextByEvent(evt);
      if (positionContext?.element?.control?.conceptId === 'mergeField') {
        console.log(positionContext);
      }
    });
