You can add an Alexa or Google Home integration to your WiZ home by going to Settings->Integrations and choosing one of these integrations.

When the integration synchronizes devices with WiZ (you may need to ask your assistant to synchronize devices, it should also happen from time to time), the contact sensor will be declared to the integration.

You will then see the contact sensor as a product in the Alexa or Google Home interface, and can use any of its traits, such as open/closed status to trigger additional automation or routines, depending on the integration capabilities.
