While during a recipe flow, should a visitor ask a FAQ while the bot is in the middle of a recipe, the bot will answer the FAQ and go back to its block inside the recipe.
Example : The bot asks the visitor his/her name, and the person asks an FAQ; it will be answered and the bot will go back to question the visitor about the name and so on.
Make sure you have added all the relevant questions and answers in the FAQ section. Check FAQ related articles to know more.
Here is a sample of a bot answering an FAQ during a recipe flow.
