deprecation of the KmlLayer class in the Maps JavaScript API

I have 550 maps with KML tracks. Got this message today from Google. What does that mean?

Hello Google Maps Platform customer,This communication informs you about the upcoming deprecation of the KmlLayer class in the Maps JavaScript API and provides the necessary resources for transitioning your applications to modern alternatives.What you need to knowThe KmlLayer functionality in the Maps JavaScript API will no longer be supported. This feature is deprecated as of today, and will be made unavailable in version 3.66 of the Maps JavaScript API, releasing in August 2026. You can keep using the KML Layer until May 2027, by explicitly using Maps JavaScript API versions that still support it.Developers are required to migrate to other ways to display geographic data like Data-driven styling (DDS) for boundaries and datasets, or client-side rendering with the Data layer. Combining the Datasets API with the new Map Management API, developers can create a fully automated pipeline for managing their geographic datasets with Google Maps Platform. By utilizing Data-driven styling for datasets, developers can not only bring their data to a map with dynamic styling, but also allow users to interact with the data.

Hi
It means there is need to read about how display that layers by new version of Google Maps API, which will change after that dates
