Uncaught TypeError: $ is not a function

Jquery sometime dont work so you need put this to fix:

jQuery( document ).ready(function( $ ) {

//you current script

});

jQuery( document ).ready(function( $ ) {
    
$(".fl-node-5eaa6adf8bae6").on("click", function() {
    $(this).css({ display: "none" });
});

});
