Just leaving this around for the future.
If you use layered icons in App Connect extensions it will break the AC panel.
You can’t add new components.
Example:
icon: [
{
prefix: "fas",
iconName: "cookie-bite",
classes: "color-yellow"
},
{
prefix: "fas",
iconName: "question",
classes: "color-green",
transform: {
size: 8,
x: 10,
y: -8
}
}
]
