Configure a webhook in your google chat: https://developers.google.com/chat/how-tos/webhooks
Feel free to customize your Webhook name and image that best suits your team :)
After that configure the extension by going to the configuration page of the extension either right click in the extension icon and select options or open the extension and click on the link.
On this page you will need to configure the chat webhook, your own name and the teamMembers.
