Please note that DVL (Data Viewer List) requires a direct connection to a table and cannot be used with Firebase directly.
For the example of the vehicles, if you want the data displayed in a DVL instead of the List Viewer then you will need a Local Data Source. You will use a list variable to store the values from Firebase and then you will loop through all the values in the list and save the values in the Local Data Source table you created. This table is connected with the DVL and the data will show in the screen this way.
I hope this is clear.
