console.log(wxp.getSystemInfoSync())

(async () => {
    const [err, systemInfo] = await wxp.getSystemInfo()
    if (err) {
        console.error(err)
        return
    }
    console.log(systemInfo)
});


(async () => {
    const [err] = await wxp.showModal()
    if (err) {
        console.error(err)
        return
    }
    
    wxp.openSetting()
