Custom components integration with Google Assistant

Hi, I developed a customer climate component (see here: https://community.home-assistant.io/t/wifi-thermostat-beok-floureon-beca-energy-component).

I have Google Assistant set up successfully and can control my lights, switches etc… My configuration file also specifically exposes ‘climate’ components and I can see my Nest on the Google Home control panel but nit my custom component…
Is there anything that needs to be declared/is required to add Google Assistant support?

Thanks

I’m not certain but I’d think the component would need to have SUPPORT_OPERATION_MODE enabled for it to work with Google assistant
