Here’s how my page looks in the DevTools (Chrome/Firefox/Edge/whatever else):

The selected button handles clicking on it, but I don’t see the corresponding handler in the DevTools. How can I find this handler in the DevTools? I have tons of JS and see no obvious way to locate suitable click handler there; hope DevTools would help me with this task. If DevTools can’t help with it, I’d like to know an alternative that could help me.
