Chat UI customization is limited. Teams can't fully control the appearance of the chat entry point, such as the launcher button, widget shape, or opening animation, and can't test different UI configurations to see what drives higher engagement. Requested behavior: Expand UI customization options to give teams full control over the chat widget's entry point appearance, including button style, size, position, colors, and other visual elements, so it integrates seamlessly with the site's design. Why it matters: A chat widget that doesn't match the site's visual language looks bolted-on and reduces engagement. Full UI control lets design teams ship a cohesive experience and test which entry point designs perform best.
