I created kml file from ArcMap and imported into my Google maps, it works. Not sure if you can open this URL: https://www.google.com/maps/d/edit?mid=13TuHmGuW9nnE-8TACTfGLdDDf6o&ll=38.90133009121122%2C-77.01476049999996&z=12
<script> var map; var src = 'https://myGoogleMapURL
should be with the .kml extension if I am not mistaken.
My question is, how do I generate kml file/url from my map URL mentioned above.
I tried adding
&output=kml at the end of the Google map URL as some people suggested but it does not work.
