X twitter icon in career sites footer

I'm trying to include the social media icons on the career sites footer. I am able to incorporate the old twitter, however the latest X (twitter) is not showing up when I add the corresponding class from fontawesome library. Is it because of the outdated library version that Oracle uses or is there a way for me to update that to the latest library?

Note: I tried appending the "link" tag with the latest version using custom java script, but the code does not seem to work.
