Currently we can only support Google+ Brand Pages and not profiles, communities, etc. so please make sure that
the Google account you're providing the details for does have a Google+ Page linked to it, otherwise we
will not be able to pull through any relevant Pages to populate this dropdown.

If you're unsure whether the page you're looking to add is a Google+ Page or a Profile, the easiest way to check
this is by looking at the page you're looking to add and, where the profile image is displayed, if there is a +1 count,
what you're looking at is a Personal Profile as opposed to a Google+ Brand Page.

Brand Pages should also display things such as a location map, contact details, etc. to represent the brand.
