[Felipe De La Puente <fdelapuente@xxxxxxxxx>]

Hi Olivier,

Thanks a lot for the help!  I wasn't aware of these documentation pages, I
was checking the webbrowser-app code to findout the properties that might
be of help for my purpose...

I definitely did nothing related to permissions so that's probably the root
cause and my next step.

I thought it was similar to C++ apps where I just used the location service
and at the first attempt to use it the permissions popup appeared...

I'll give it a try and come back with more details if it doesn't work.

Best Regards,
Felipe.
