Hello, I'm new to the Discord, I hope you're well, I hope you're well. I'm currently setting up a chatbot on my site using Botpress and I'd like to include a specific feature. I'd like it to automatically pop up above the chatbot icon when a user arrives on the site, inviting them to start a conversation. In addition, I'd like the chatbot to send a first automatic message five seconds after the user arrives on the site. I've looked through the Botpress documentation, but I can't find any clear instructions on how to set up this feature. Could you give me some guidance on how to implement this? If necessary, are there any examples or tutorials I could follow to achieve this goal? Thank you in advance for your invaluable help.
