How to change the react icon from smily to something else

    I would like to have everything simple so I would like to only have one thumbsup button instead of many reaction options. I have done everything but one .. and that is changing the icon from smily to a thumbs up. I used these CSS codes but there has been no differences:

    .fa-thumbs-o::before { content: "\f164"; }
    .reactButton { content: "\f164"; }

    I would appreciate any help :) :thumbup:
