Opening the extension tags and creating a new tag show that you can decide an icon.
A link suggest to take the fa fas code visiting https://fontawesome.com/icons?m=free
Now for example I want use this icon:
https://fontawesome.com/icons/people-group?f=classic&s=solid
or this:
https://fontawesome.com/icons/users-line?f=classic&s=solid
but every code suggested by the site doesn't work.
Tags is not very clear on how have the right code that works, on my opinion.
