I get the notification to upgrade Marker in my generic javascript code.
However I don’t really understand how to modify the script to have AdvancedMarkerElement instead of Marker.
This code is completely generic and loads data from Mysql
The documentation is not very clear on the subject and requires some explanation to proceed with the upgrade
