How to use the jeepney.integrate.blocking.connect_and_authenticate function in jeepney

with closing(dbus_init()) as conn:
	          collection = secretstorage.get_default_collection(conn)
	          items = collection.search_items({'application': 'myapp'})

	   However, you will not be able to call any methods on the objects
	   created within the context after you leave it.

	.. versionchanged:: 3.0
	   Before the port to Jeepney, this function returned an
	   instance of :class:`dbus.SessionBus` class.

	.. versionchanged:: 3.1
	   This function no longer accepts any arguments.
