Google Nest Community

I selected default source but doesn’t allow me to choose witch songs or playlist?

Hi I own the nest Camera and wanted to subscribe to the Nest Aware subscription for $12 but before I do how do I know what version of camera I own before I subscribe to the $12 subscription vs the $6.00?

On the Alexa Speaker, the Amazon devices talk but getting a Google Product to talk on Alexa or Google I can never do.
