HI Team,

I am trying to implement co browse for voice, currently i have taken the sample code from developer forum, added co browse under contact center and using the same deployment key, i will attach the code i am using and screenshots of errors, for your reference, please look into it. I have hidden some details in below code,

Simple co-browse with voice example
<h1>Simple co-browse with voice example</h1>

    <button type="button" id="start-cobrowse" onclick="genesysWebchat.startCobrowse()">Enter Co-browse Security Key</button>

<!-- Div with this id required to display security key form -->
<div id="cobrowse-security-form"></div>

<!-- Co-browse with voice uses the webchat API, so include it here -->
<script src="https://apps.usw2.pure.cloud/webchat/jsapi-v1.js" type="text/javascript"></script>

<!-- For co-browse with voice, you must load the co-browse API. Co-browse with web chat loads the co-browse API for you. -->
