These three issues are kind of connected. They&#x27;re requesting you your Google account email so they can associate your account with their private beta (available in the Chrome store) and let you install it from the Chrome&#x27;s webstore.<p>You can go the other way around and &quot;build&quot; it. Just clone their repo and point Chrome to the cloned directory so that it knows that there&#x27;s an unsigned extension there. Done.
