How to listen to events from Verge to javascript and send inputs to it

We are looking for a way to send some data to v3d app using javascript and to listen for events:

So a practical example could be that we have a 3d, and when we send data to it it does some action like focus on some element inside 3d.
Similar, when something is clicked inside 3d we want to get that in javascript.

Is this possible and how to do it, I can share some code details what we do.

Pseudo = we load visual_logic.js file and then we init scene, but haven’t found any docs how to pass data and to listen for some events.

If anyone knows something or some example it would be nice to hear from you.

Best, Miroslav
