A non-Google application (more precisely an app that doesn't share an app
group with Chrome) launched Chrome with an http or https URL. This can
happen on iOS 14+ when Chrome is set as the default browser and a system app
(f.e. Messages) or an app from a 3rd party developer opens a URL.

</enum>
<enum name="MobileSessionStartAction">

Logged when an application passes an http URL to Chrome using the custom
registered scheme (f.e. googlechrome).

registered scheme (f.e. googlechromes).
