Improve Button Interaction Feedback in the Chatbot

To improve the user experience, action buttons (e.g., Approve, Reject, create) should become disabled (greyed out) after they are clicked.

Currently, after a user clicks a button, the bot sends a confirmation message (e.g., "Thank you for approving"), but the button itself remains active. Sometimes This can leave users unsure whether their action was successfully registered and may lead to repeated clicks.

Disabling the button after it is selected would provide clear visual feedback, prevent duplicate actions, and create a more intuitive and seamless user experience.
