I've searched for a long time after this answer but can't find anything to help me.

<button onclick="myFunction">Press Me</button>
<script>

    function myFunction(){
        //Adding 1 to the variable.
    }

</script>

How can I create a variable that stores how many times this button has been pressed in total by all users? I know you can use localStorage but that only saves how many times a certain person has clicked on the button. I want to see how many times it has been pressed in total by all users and make it into a variable.

Thanks
