You can find connected elements via the outgoing & incoming properties of any element.

const eventBus = modeler.get("eventBus");

eventBus.on("element.click", function (event) {
  const { element } = event;

  console.log("element clicked:", element);
  console.log("element id + name:", element.id, element.businessObject.name);
  console.log("incoming (before):", element.incoming);
  console.log("outgoing (after):", element.outgoing);
});

This way you can go along the chain and potentially find those elements.
