How to open wechat and open link in it from browser mobile

I use this code to open wechat from chrome browser:

<a href="weixin://">
    <button>Open wechat</button>
</a>

I try to use weixin://dl/businessWebview/link/url=www.google.com to open link google.com. But when open in wechat, there is an error "invalid_source". What is the best way to do it?

It has been deprecated for several years now - there is no way to reliably achieve this functionality at the time of writing.
