确认短信上的电话预览URL:生成假验证/ PHP

we have a created for a client a web app (PHP) for meeting scheduling.

We send SMS to users in order to confirm their meeting, with a link to click to confirm their meeting.

Most of user have enable website preview in SMS on their phone.

How can I checked that the page is loading from a phone 'sms browser previewer' OR is really clicked / loaded by a human ?

A simple get_browser could not help, because browsers previewers are often the browser of the user... and it's not a bad robot crawling something..

The client's process is : the user click the link received on his phone, the meeting is confirmed.

Any tips ? Can't find any idea how to detect that and prevent 'false validation'.

thanks !

    Thanks, cookie trick works :

    in wp function :

       function set_new_cookie_conf() {
        setcookie( 'confirm_cookie', 'human', time() + 3600, COOKIEPATH, COOKIE_DOMAIN );
    }
    add_action( 'init', 'set_new_cookie_conf');
    

    in confirm function :

     if(isset($_COOKIE['confirm_cookie'])) {
                   //DO THE JOB
    
                 }
