External links

To add an icon to external links that appear in the left sidenav, follow the format below in the astro.config.mjs file.

{
    label: 'Open Payments API',
    link: 'https://openpayments.guide/',
    attrs: {
        target: '_blank',
        rel: 'noopener noreferrer',
        'data-icon': 'external',
},

Et voila
