If monitorEvents is not working, you can log events with the help of "Event Listener Breakpoints". "Event Listener Breakpoints" in the Sources tab will stop code execution when the breakpoint is triggered. This is unhelpful for some events like touchmove.

The code the breakpoint stops at likely has access to the event that was triggered as a parameter. You can log this by adding a 'logpoint' in the line and log the event variable.

You can then then remove the breakpoint and the logpoint will log the events in the console without blocking stopping execution.
