mod_googlemeet aee7f41 uses MESSAGE_DEFAULT_ENABLED but this was only introduced in Moodle 4.0 (MDL-67853).

For Moodle 3.11 you can work around this issue by editing mod/googlemeet/db/messages.php changing lines 30 and 31 to:

            'popup' => MESSAGE_PERMITTED + MESSAGE_DEFAULT_LOGGEDIN + MESSAGE_DEFAULT_LOGGEDOFF,
            'email' => MESSAGE_PERMITTED + MESSAGE_DEFAULT_LOGGEDIN + MESSAGE_DEFAULT_LOGGEDOFF,
