Using extra css_files with Tabulator - does not work when deployed on a server

I’m quite new to panel, and have been designing tables with the Tabulator option. My table is fairly simple, quite similar to the ones presented in the documentation , with a few icons in my table. This table is shown below

I am therefore using the following line to use import the fontAwesome icons.

pn.extension('tabulator', css_files=[['font-awesome']])

I have also tried using this line, in attempting to debug my problem:

pn.config.css_files = [['font-awesome']]

In both cases, when I execute my code locally using panel serve, this works perfectly. But in both cases when I deploy my code on a server, the icons do not show.

Any ideas on how to solve this ?
Thanks !
