gr.Chatbot - Bind share button to user function

[Steveolas]

• [ ✔️ ] I have searched to see if a similar issue already exists.

Gradios gr.Chatbot has a show_share_button parameter that from my understanding has very limited use whithin huggingface spaces. I would like to be able to map this button to whatever function I like, with an event listener such as .share. Same as exists for the other buttons such as like, clear reset and undo.

Even better, (and more complicated) add a posibility to add custom buttons whithin the chatbot, both in the bot level (such as clear and share are cutrrently) and in the message level (such as cope, undo, retry). Let the user add their own icon and bind that button to their own function

Seems to me like implementation should not be to complicated because the process to making such buttons already exists, but I am not familiar with the source code.

Thanks
