problem with icon fontawesome

[leanndamiann1]

What's up guys, add in extra.less the code to show icons in the navigation and also icons in the part of entering and registering,... but it doesn't show me, do I have to install an addon?

// Login
.p-navgroup-link.p-navgroup-link--textual.p-navgroup-link--logIn:before {
    font-family: 'Font Awesome 5 Pro';
    font-size: inherit;
    font-style: normal;
    font-weight: 400;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    content: "\f090";
    width: 1em;
    display: inline-block;
    text-align: center;
    color: #E6BB5C;
}
// Register
.p-navgroup-link.p-navgroup-link--textual.p-navgroup-link--register:before {
    font-family: 'Font Awesome 5 Pro';
    font-size: inherit;
    font-style: normal;
    font-weight: 400;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    content: "\f084";
    width: 1em;
    display: inline-block;
    text-align: center;
    color: #E6BB5C;
}
