Hi there!

Thanks for contacting us.

If you want font awesome icons there then please use the following code in your custom CSS:

[class^="icon-"]:before, [class*=" icon-"]:before {
    font-family: 'Font Awesome 5 Free';
    font-weight: 600 !important;
        }

Note: Path towards custom CSS(Joomla 4): System>Site Templates Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
