How To Add a Floating Contact Form Button in WordPress To Collect Leads For Free?

I want something of contact floating on the right side of screen. There are four items in the floating contact, when people click on each of them, they will expand. For example, the first item is Whatsapp, when that item is clicked, the whatsapp qr code will expand. I don't know what plugin can do this.

Nice 🎉

Is there a way to add recaptcha to contact form??

can we choose redirect to whatsapp directly after submit form?

Truly good leads generation and local storage idea
