## Third-Party login

```javascript
window.chatWidgetApi.thirdDIDLogin(address, thirdSignFunc, callBack)
```

| Method Name                         | Description         | Parameters                                                                                                                                                                                                                 | Return Values |
| ----------------------------------- | ------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------- |
| window\.chatWidgetApi.thirdDIDLogin | Inject login status | <p><code>address</code>: user wallet address;</p><p><code>thirdSignFunc</code>: Third party signer, eg.  <code>thirdSignFunc({ message})</code>;</p><p><code>callback</code>: callback function after successful login</p> | N/A           |

1. First, set `useThirdLogin` on the widget component: `<chat-component useThirdLogin={true} />`.
2. Call this API and provide the necessary parameters after the component has mounted, such as using *useEffect*, *ComponentDidMount* in *React*, or mounted in *Vue*. The `address` parameter represents the wallet address of the logged-in user (required), and `thirdSignFunc` is the signing function (required). When the API internally calls the `thirdSignFunc` signing function, it will pass the parameter `message`. `thirdSignFunc` should use this message to trigger wallet signing and return the result of the signature. The `thirdDIDLogin` API will wait for `thirdSignFunc` to complete and return, and then proceed with the login logic. Pseudocode example:

```javascript
thirdDIDLogin(address, thirdSignFunc, callback) {
    // Use address to call the the API and retrieve the corresponding DID.
    const sign = await thirdSignFunc({message});
    // Call didLogin(sign, ...otherParams) to perform the login.
    // Upon successful login, call callback();
}
```

3. The `callback` parameter is optional and can be used as needed. It will be invoked regardless of whether the login is successful or not. For a successful login, call callback(true), and for a failed login, call callback(false).
