Facebook Share not opening in APP

Goodmorning,
All the social share if clicked in mobile open IN THE APP of the social.
All BUT Facebook which opens as a browser link…
Any Idea how to fix this?

I tried this code found online but works very badly (app doesn’t open in the profile)

<script>
(function($){
    var a = function() {
        var isMobile = '';
        if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) && 'ontouchstart' in document.documentElement)
        {
          isMobile =  true;
        }
        else
        {
          isMobile =  false;
        }

        if(isMobile || $(window).width() <= 767) {
            $('#top #wrap_all .av-social-link-facebook a').attr('href','fb://profile/476685389485016');
        } else {
            $('#top #wrap_all .av-social-link-facebook a').attr('href', 'https://www.facebook.com/GDGpropertysolutions/');
        }
    }

    $(window).resize(function() {
        a();
    }).resize();
})(jQuery);
</script>

Thank You
