Hi, as David wrote, the logged_in_user object will do it!
In order to make it more visual, maybe, here is an example for Intercom and Crisp
Also, here is a script I use for getting the user info while using Sendinblue Chat (check the last part of the code)
<script>
(function(d, w, c) {
w.SibConversationsID = '60d0428bb9cxxxxxxxxxx';
w[c] = w[c] || function() {
(w[c].q = w[c].q || []).push(arguments);
};
var s = d.createElement('script');
s.async = true;
s.src = 'https://conversations-widget.sendinblue.com/sib-conversations.js';
if (d.head) d.head.appendChild(s);
})(document, window, 'SibConversations');
</script>
<!-- /Sendinblue Conversations {/literal} -->
<script>
SibConversations('updateIntegrationData', {
email: window['logged_in_user']['softr_user_email'],
firstName: window['logged_in_user']['softr_user_full_name'],
});
</script>
