Another approach, how to remove this parameter (so your users can share your URL without removing it manually) is to use JavaScript and history.replaceState.

Code from link:
(function() {
var param = 'fbclid';
if (location.search.indexOf(param + '=') !== -1) {
var replace = '';
try {
var url = new URL(location);
url.searchParams.delete(param);
replace = url.href;
} catch (ex) {
var regExp = new RegExp('[?&]' + param + '=.*$');
replace = location.search.replace(regExp, '');
replace = location.pathname + replace + location.hash;
}
history.replaceState(null, '', replace);
}
})();
