Chat UI Rendering on Mobile

Is there a way to modify how the customer facing chat UI renders on mobile devices? Right now, when we pop a pre-chat form or if the customer initiates a chat, the UI takes up the entire screen of the mobile phone. We use other chat applications that allow the chat UI to take up the lower half of the screen which allows customer to continue to interact with the website during the chat interaction. From what we can tell, once Bright Pattern chat is open, it completely obscures the website and there is no way to minimize it to get back to the website.
