I am using Freshworks Chatbot in my application what I need is I've to hide the close button when a user submits the form in the bot.

I've tried two ways:

First:

<script>
  $("#thankyou-button").css("display", "none");
</script>

Second: Added this CSS line in style tag.

#thankyou-button {
    display: none;
  }

None of these approaches are working. Check this on Code link
