Improve Discoverability of Manual Input Editing Controls in Chatbot

Manual input editing controls in the chatbot interface, such as the icon used to modify an existing input value, are not visually discoverable to users today, which can make it difficult for users to realize that editing is possible. This enhancement would redesign the manual input editing affordance to be more visible and intuitive, such as through clearer iconography, labeling, or persistent visibility rather than a hidden control. Improving discoverability of this function would reduce user confusion and support a more efficient, self-explanatory experience when building or adjusting chatbot automation inputs.
