Auto Dial a phone number from web application on mobile browser

I want to create a link on my html page for a phone number, such that clicking on that number will start a phone-call.

Using anchor tag with href="tel:{phone number}" we can create a phone-link, but in mobile browsers, clicking on such link will open dialer-pad and show user to save to contact or make a call option.

I want to avoid all those things, instead clicking on number should auto-dial it and start a call (the way we have it on whatsapp call)

anyone has any suggestions here.

Thanks.
