NewReleases can send notifications directly to your Google Hangouts Chat room or even multiple rooms.
The integration is done using Google Hangouts Chat Webhooks. You would need to generate a new Webhook and add it to NewReleases on Hangouts Chat settings page.
More details on how Hangouts Chat webhooks work and how to use them are on the official documentation page.
NewReleases will send messages only about new releases of the project that you configured with Hangouts Chat notifications, a message when you enable the integration and one on integration removal. No other type of messages will be sent.
By using a webhook integration, NewReleases is unable to access room's content which ensures complete privacy.
The proper way to remove Google Hangouts Chat integration is from the same Settings page where you have enabled it. It is possible to enable and disable NewReleases Google Hangouts Chat integration unlimited number of times for any room that you want.
