Hi,

Adding an external script to Odoo POS v.15 has gotten a bit simpler. No more fussing with separate asset files. Now, you can just dive into the manifest file and do the deed.

Here's a snippet of what you'll want to pop into your __manifest__.py file:

'assets': {
    'point_of_sale.assets': [
        'https://app-sandbox.duitku.com/lib/js/duitku.js',
    ],
},

With this snippet, you're basically telling Odoo, "Hey, grab this external JavaScript file (`duitku.js`) and add it to our project's assets." Just make sure that URL is spot-on and accessible.

Hope this helps
