Maps Notification ETA info extraction

I’m relatively new to KWGT but am finding it incredibly useful and have managed to create several widgets for my home screen for my Android car headunit.

I have run into an issue though with extracting data from the Google Maps Navigation notification.

I can get everything I need except to top line with the journey time, distance left and ETA in it.

See image below of what I can extract with the various ni options within KWGT.

I figured the Journey data should probably be $ni(com.google.android.apps.maps,desc)$ but that gives me nothing at all.

I can extract the ETA data in Macrodroid where that data is in {not_sub_text} so at the moment I am using Macrodroid to extract it and pass it to KWGT using the tasker/locale plugin, but it would be much cleaner if I could extract the data directly in KWGT.

Any help greatly appreciated
