The primary tab of the Digital Assistant is the Chat tab, which allows you to directly speak to your Assistant.
Digital Assistant uses NLP and a list of pre-trained sentences in order to naturally understand user requests. For example, if you say Show me my news then the system will automatically request the latest data from the app that's responsible for news in your organization.
Go ahead and try to ask the Assistant something else, e.g. "Do I have any pending approvals?" or "Show me open issues"

When Demo Mode is active you will see a little flag at the bottom of the webapp:
