Is sp-picker now official?

Photoshop UXP Plugin API
8

Does no onChange work with these components? I try to open a dialog box on photoshop using react, javascript and UXP. I can not get the value of the selected menu item. How can I achieve this? @Karmalakas

const DialogContent = ({dialog}) => {
  return (
    <>
    <sp-picker label="Label">
    <sp-label slot="label">Please select a reason</sp-label>
    <sp-menu slot="options" onChange={handleSelection}>
        <sp-menu-item value="value1" selected={true}>{options.item1}</sp-menu-item>
        <sp-menu-item value="value2">{options.item2}</sp-menu-item>
        <sp-menu-item value="value3">{options.item3}</sp-menu-item>
        <sp-menu-item value="value4">{options.item4}</sp-menu-item>
    </sp-menu>
    </sp-picker>
  
    <sp-footer>
        <sp-button onClick={() => dialog.close()}>Close</sp-button>
    </sp-footer>
    </>  
  );
}
