Google Nest Hub voice commands Netatmo Presence

My Netamo Presence camera iworks with Homey.
I can cast a snapshot from Netatmo Presence by Homey Flow to Google Nest.
But a livestream that’s not possible.
When I say to Google HUB ‘Let Camera Front door see’ the Nest hub gives the stream.
Is there a possibility to send a spoken command to Google Nest by Homey ?
Without the voice of Homey off course. I wan’t toget rid of the talking …
