# Init DiscoveryInfoProvider
self._discovery_info_provider = DiscoveryInfoProvider()
self._discovery_info_provider.configureEndpoint(<HOST>)
self._discovery_info_provider.configureCredentials(<ROOT_CA_PATH>, <CERTIFICATE_PATH>, <PRIVATE_KEY_PATH>)

gg_connector = GGConnector(
    self._shadow_client, self._discovery_info_provider)

try:
    core_info, group_ca_path = gg_connector.discover(<THING_NAME>)

    gg_connector.connect(
        core_info, group_ca_path, <CERTIFICATE_PATH>, <PRIVATE_KEY_PATH>)
except BaseException as err:
    logger.error(err)
