const cozeWebSDK = new CozeWebSDK.WebChatClient({
config: {
isIframe: false,
type: "app",
appInfo: {
appId: "xxxx",
workflowId: "xxxx",
parameters: {
user_id:'xxxxx',
},
},
},
componentProps: {
title: "小田AI",
},
auth: {
type: "token",
token: 'xxxxx',
},
ui: {
chatBot: {
isNeedAudio: true,
},
base: {
layout: "mobile",
lang: "zh-CN",
zIndex: 1000,
},
header: {
isShow: false,
isNeedClose: false,
},
asstBtn: {
isNeed: false,
},

footer: {
isShow: false,
},
},
})
setTimeout(() => {
cozeWebSDK.showChatBot()
}, 100)

## The current behavior

直接在浏览器打开是正常的。

但是在 RN 中报错 CozeWebSDK is not defined，切换版本到 1.1.0-beta.3 是正常的。但是 1.1.0-beta.3 不支持语音输入功能

## The expected behavior

期望 1.2.0-beta.14 能正常使用。

No repository file or test is named. Reproduce the CDN integration in the supplied HTML and React Native WebView context, comparing 1.2.0-beta.14 with the referenced 1.2.0-beta.8 CDN script and the working 1.1.0-beta.3 version. Done means the current SDK exposes CozeWebSDK and supports the reported voice-input configuration in React Native.
