How can we tell which countries are allowed for the user by the account admin?
E.g. the admin might have limited the account to only use Global dial-in countries as [US, Argentina & Australia], out of which the user had selected only [US, Australia] in their own “Global dial-in countries” on their own settings.
How can we know this information, so that for the user selecting the dial-in countries,
a) we don’t show other countries that the admin did not allow?
b) the countries they had already selected on their own profile settings are shown as “selected”
