When hover, a bullet box is displayed below the node

import BpmnViewer from ‘bpmn-js/lib/NavigatedViewer’;

Now, I have built a viewer using the above method of introduction.

Now I’m wondering if I can achieve such a function, when a user hover a node, a pop-up box appears, showing some information of the current node.I found an example of the comment function. So, I feel that I can also achieve the function I want. Now I don’t have any ideas. Can you give me some suggestions?Thank you very much.

Interaction Events + Overlays = :fire:

Thank you for your help. These have given me some ideas. Thank you very much.
