class CustomComponentWrapper() : CustomComponent() {
    override public fun setCompositionRoot(compositionRoot: Component) {
        super.setCompositionRoot(compositionRoot)
    }
}

fun customComponent(init: CustomComponentWrapper.() -> Unit = {}) = CustomComponentWrapper().apply(init)

with that, you can add a customcomponent like that:

customComponent {
    textField()
}
