Summary: Added scheduler to scan the Native UI every 500 ms to test, Also added instrumentation in a separate event with the timings of each stage visualised in a Data table on desktop which can be accessed with ctrl+I. Currently this instrumentation event is sent every time but it could be a config option controlled from the desktop in the future
