Webview - how to display google map

Hello,
I’m trying to display a google map URL. Something like this:

https://www.google.com/maps/@44.9574335,-93.2850498,14.21z

So, I simply put in my sitemap:

  Frame label="map"
  {
    Webview url="https://www.google.com/maps/@44.9574335,-93.2850498,14.21z" height=16
  }

When I go to it with my browser, I see a big square where the webview would be, but no map. I see others have had the same issue before, but I haven’t come across a fix. This is on OH1.8.
