SDK intergration in iOS

I am loading this url in WKWebView for tiledesk intergration in iOS. Chat it is working fine. But I have one quesion how do I pass user name and email address without pre-chat form.

I suggest you to use the new v5 Widget SDK see here: Web SDK - Tiledesk Docs

and pass the parameters userEmail and userFullname as URL parameters as defined here: Web SDK - Tiledesk Docs
