From my understanding, all Font Awesome icons should work with linking this bootstrap stylesheet. But, I just got that one .fa fa-deskto to work, others do not display, the second one for example is:
https://fontawesome.com/icons/bath?f=classic&s=solid
Both icons are also free, but it isn’t working.
