MMM-GoogleAssistant Custom Actions not working

[Lorenzo_Zappa]

Hello, I have successfully installed this module and everything is working like a charm (this is the module: https://github.com/gauravsacc/MMM-GoogleAssistant).
However lately I created some custom actions using google assistant sdk (following this guide: https://developers.google.com/assistant/sdk/guides/library/python/extend/add-trait-and-handler), and they work perfectly with google assistant, this is the command I use:

python hotword.py --device_model_id my-model

The issue is that they don’t seem to work with this module. If I invoke my custom action using the module, it recognizes it as a known action (that means that the actions.json file has been correctly uploaded, indeed I can see my actions in my google project page, so far so good) but it doesn’t run the commands saved in my hotword.py file.
I basically don’t know where to save that file in order to get used by this module.
Thank you for your help
Lorenzo
