Why do I see charging stations marked by different icons and symbols?

Different icons indicate different scenarios:
● White Pin: A charging station you are currently using
● Thunder Icon: Fast charging station with Power higher than 19.2 kW
● Commercial Partner Logo: Charging station near Enel commercial partners are shown with specific icons corresponding to the category of activity (bars and restaurants, hotels, supermarkets, shopping centers, and entertainment centers)
● Grey Pin: The charging station is managed by other operators
