You can also use Waze - just add a Frame widget with an URL like:
https://embed.waze.com/en/iframe?zoom=12&lat=52.50912&lon=13.43456
You have a header and footer button that you can’t remove but it’s better than nothing.
You can go to https://www.waze.com/en/livemap to recenter the map and get a permalink with the coordinates and zoom (button in the bottom-right corner).
