Custom script for frontend

Hi,
I have just installed the self-hosted version as a test for some clients.

I’ve noticed that Custom CSS in the settings for Customer Portal - is there a way to also add custom script (apart from Google Analytics).
I’m looking to add Tawk.to code snippet so that the public visitors have the option of receiving direct support/interaction when they are viewing their invoices etc.

I found a previous thread referring to place the code in:
resources/views/public/header.blade.php

It seems like that file location has moved and I tried placing the code in:
resources/views/header.blade.php but was unsuccessful.

Any ideas?

Thanks in advance.

It should be the /public file, the other file is for the admin section.

Great, thank you Hillel.

For other who might find this thread, the correct file location were:
resources/views/public/header.blade.php

I added the Tawk.to script at the bottom (just before the closing tag </script>):

<!--Start of Tawk.to Script-->
var Tawk_API=Tawk_API||{}, Tawk_LoadStart=new Date();
(function(){
var s1=document.createElement("script"),s0=document.getElementsByTagName("script")[0];
s1.async=true;
s1.src='https://embed.tawk.to/xxxxxxxxxx/default';
s1.charset='UTF-8';
s1.setAttribute('crossorigin','*');
s0.parentNode.insertBefore(s1,s0);
})();
<!--End of Tawk.to Script-->
