Taking your screenshot into reference, You may try add this to custom css field or override.css as per documentation here
.fa-chevron-left::before {content: "\f053";}
.fa {display: inline-block;font: normal normal normal 14px/1 FontAwesome;font-size: inherit; text-rendering: auto;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;}
.fa-chevron-right::before {content: "\f054";}
Although, It is quite necessary to have external file reference for fontawesome as outlined in tutorial above for fontawesome icons to appear if the same is not present in the head section of your website
