I tried to add a Javascript code but it's showing on the website as plain text.
This was the code
<script>
!function (t, e, c, n) {
var s = e.createElement(c);
s.async = 1, s.src = '
https://scripts.claspo.io/scripts/' + n + '.js';
var r = e.scripts[0];
r.parentNode.insertBefore(s, r);
var f = function () {
f.c(arguments);
};
f.q = [];
f.c = function () {
f.q.push(arguments);
};
t['claspo'] = t['claspo'] || f;
}(window, document, 'script', 'E5E2B38DCE9449C290CB6A52B2154B45');
</script><script>claspo('init');</script>
