Get twitter icon and link for each author in pkgdown

Hi,
I would like to add twitter icons with link for each author (as is possible for the ORCD icon and link).
Is this possible and in that case how?

Thanks in advance.
John

I think this strategy would work. You'd have to fiddle with the CSS font-size and color:

In the pkgdown.yml:

authors:
  First Last:
    html: "<br/><a href='https://twitter.com/twitterhandle'><span class='fab fa-twitter twitter' aria-hidden='true'></span></a>"

Thanks for the help, but I don't get it to work.
I got the icon and link to work, but then the Name disappeared.

In the DESCRIPTION file I have:

Authors@R: c(
    person("FIRST", "LAST", , "FIRST@gmail.com", role = c("aut", "cre"), 
      comment = c(ORCID = "XXXX-XXXX-XXXX-XXXX"),
    )

And as you suggest in the _pkgdown.yml I added:

authors:
  FIRST LAST:
    href: https://website.com/
    html: "<br/><a href='https://twitter.com/twitterhandle'><span class='fab fa-twitter twitter' aria-hidden='true'></span></a>"

Can you see if I am doing something wrong.
Thanks for all the help!
