extraControl is not working. I want to add extracontrol cutom button in the Footer

[priyangamani]

Is there any way to customize the footer?

const handleBtn=()=>{
}

<ChatBot
   extraControl={<button onclick={handleBtn}/>}
  steps={{
      id: 'query',
        user: true,
      trigger:2,hideExtraControl: false,}}

Is there a solution to do that? Thanks!
