No Input Box Validation, User can press send even if its an empty space.


Also we can add a disable state which will be true untill model replies with answer. And for mean time we can keep both input box and button disabled.

Find the input component and send button in the frontend code, likely in a React component. Add validation to check for empty or whitespace-only input before enabling the button. Also implement a disabled state for both input and button while waiting for the model's response. Look for existing state management related to the chat input and model reply status.
