MMM-Google Assistant

[Chris]

Hello,
I am trying to install this module but I am having problems with a step of the installation of the Google Assistant SDK.
(https://developers.google.com/assistant/sdk/guides/library/python/embed/register-device)
Everything is fine until the step “Register the Device Model”.
Indeed, when I use the registration tool, it does not work.
I tried the command:

(env) $ googlesamples-assistant-devicetool register-model --manufacturer "Assistant SDK developer" \
          --product-name "Assistant SDK light" --type LIGHT --model my-project-1505046981535-my-model1

Each time I have the following error message:

Error: Error loading client secret: [Errno 2] No such file or directory: 'client_secret_xxxxx-m88slnqk24bqul282n0nnogs10sck6qo.apps.googleusercontent.com.json'.
Run the device tool with --client-secrets or --project-id option.
Or copy the client_secret_xxx-xxxx.apps.googleusercontent.com.json file in the current directory.

Could someone tell me the procedure to follow?

Thank you in advance,
Regards,
