I need help to continue a driver tracking project

I need help to continue a driver tracking project.
I already have a working start, but I can’t continue, I’m stuck at “call Google_Maps1.Add Markers”. I can’t continue.

You need to explain what you have already tried and show the relevant blocks so you can receive help.
Did you search here in community ?
There are many topics about.

sorry, I forgot to attach the images
This part will bring me the “tag” and location, moving the camera to the person’s location. But, I don’t know where to add the “Add Markers”. Or is it correct?
