+#### Mobile and geolocation
+
+This snippet emulates Mobile Safari on a device at a given geolocation, navigates to maps.google.com, performs action and takes a screenshot.
+

+print(iphone_11)
+
+async def run():

 #### Evaluate in browser context
 
 This code snippet navigates to example.com in Firefox, and executes a script in the page context.
