Does anyone know how I can make different icons for the Thank you! and Like reaction? When I use this code in Custom Styles: .sys-icon.thumbs-up:before, .fa-thumbs-up:before{content: url("--"); } I end up changing both Thank you and Like Thumb up icons... (screenshot attached)

And another question: does anyone know how I can deactivate the pop-up with other reactions?

I need to have two buttons with two different icons.
