how to set Einstein Chat Bot size in Utility item Screen ?

@PRITAM GOHATRE

You would use custom CSS within your component to define the size.

CSS:

/* myComponent.css */
.chatWindow {
    width: 500px; /* Set your desired width */
    height: 600px; /* Set your desired height */
}

VF:

<apex:page>
    <style>
        .chatWindow {
            width: 500px; /* Set your desired width */
            height: 600px; /* Set your desired height */
        }
    </style>
    <!-- Your chatbot embedding code here, ensure it has the class "chatWindow" -->
</apex:page>

LWC:

<template>
    <div class="chatWindow">
        <!-- Your chatbot embedding code here -->
    </div>
</template>

You can adjust the panel width and height for utility items in the Utility Bar settings, which indirectly affects the chatbot size.
