Mark up your content to reach users on Google Assistant and Google Search.
Structured data tells Google about the type of content you're creating, so we
can present it to users in an interactive way. A Frequently Asked
Question (FAQ) page contains a list of questions and answers pertaining to
a particular topic. If you own an FAQ page, mark up your content with the
FAQPage schema type so we can present your content to users
who search Google for that topic.
In addition to presenting your content as a rich result on Google Search, we can read your markup to automatically build an FAQ Action that presents your content on the Google Assistant. When users ask the Assistant a question that your FAQ content can answer, we may direct them to your Action.

structured data guide.
