Amazon Connect Chat now provides additional options to customize the out-of-the-box chat widget, enabling you to add a logo and change fields such as ‘System Message’, ‘Bot’, ‘Text Input Placeholder’, and ‘End Chat’. You can also further customize the widget using CSS (Cascading Style Sheets) to change visual elements like the size of the widget, font size and color so you can easily align the widget with your website branding.
