Delay to the bot responses

Hi everyone! I am designing a Chatbot and it will be deployed to Google Chat. However, to make it more human-like I want to add delay to the responses. I checked “reminders” on the Rasa page however it does not seem to be relevant to what I want. I tried time.sleep() but even though it does not give any error it did not work. I tried to follow this discussion Messenger Game: Delay Bot Responses - #2 by ChrisRahme but I couldn’t understand propoerly.

I appreciate your suggestions and help!
