Change icon

It is not possible to add other icons to the app, but you may upload your icon font somewhere else and then use CSS to replace the icons.

In the example the FontAwesome "thumbs-up" is replaced with the star from Atlassian icons:

.content-rating-icon.fas.fa-thumbs-up {  
    font-family: var(--aui-icon-font) !important; 
    content: "\f1aa" !important;
}
