When add centerbox

Have you read through the documentation?

• [x] Astal docs
• [x] Library references
• [x] FAQ

Describe what have you tried so far I have followed the installation instruction from astal docs for Arch Linux. When use my widget alone in a bar ags start as expected. But when add a centerbox tag to add more widget ags give me an error:

import { App, Astal, Gtk, Gdk } from "astal/gtk3"
import  Workspaces  from "./Workspaces"
import Clock from "./Clock"

export default function Bar(gdkmonitor: Gdk.Monitor) {
    return <window
        className="Bar"
        gdkmonitor={gdkmonitor}
        namespace="bar"
        exclusivity={Astal.Exclusivity.EXCLUSIVE}
        anchor={Astal.WindowAnchor.TOP
            | Astal.WindowAnchor.LEFT
            | Astal.WindowAnchor.RIGHT}
        application={App}>
            <centerbox>
                <Workspaces />
                <Clock />
            </centerbox>
    </window>
}

Describe your question I don't understand how use centerbox tag, I had also try to add example's bar from this repository but ags return the same error.

Center box expects exactly three children, you specified only two.

The centerbox should be made more liberal in how many children it accepts though.
