Font awesome not displaying non-core icons?

Question

css

For example, the code
i.fas.fa-arrow-right
gives an arrow, it is displayed normally, the same with a heart,

but the code
i.fas.fa-comment-alt-dots
does not display what it should ,
a link to the icon:
https://fontawesome.com/icons/comment-alt-dots?sty...

Answer 1

A pro license is required, which is written right next to the name of the icon. The free version does not have this icon.

Answer 2

It is available for a pro subscription. If you have it, then download the appropriate bundle. If not, then look for such an icon on the side.
