How can I increase the size and change the position of the embedded AI agent on my site?

I've created an AI agent using the pro plan and embedded it into my website. However, the AI is closed, too small, and located in the far right corner of the website. How can I keep the Ai agent open so that it's a larger size with the preloaded questions visible to the user, and how can I change the position so that it's located above the fold, right above the Book a Demo button? Here's a link to the site with the AI agent: https://www.limitlessgrowthsolutions.com/
