The chat integration uses a public JavaScript API of the selected chat provider. You have to install the chat widget into your application as you would normally do without Product Fruits integration in place. Then follow this article.
Follow Freshdesk docs on the installation topic. Then update the code according to these docs.
Change the Freshdesk init script to hide the default Freshdesk launcher button.
window.fcWidget.init({
"config": {
"headerProperty": {
"hideChatButton": true
}
},
"token": ...,
"host": ...
});
Add a custom CSS to hide the default launcher button.
<style>
#launcher-frame { display: none !important; }
</style>
