I am using the latest version zoom-sdk-android-5.16.2.16555, and to create a JWT token, I use the website [https://jwt.io](https://jwt.io/) with **header** as:  
{  
“alg”: “HS256”,  
“typ”: “JWT”  
}

```auto

**payload** :

```

{  
“appKey”: “---------------”,  
“iat”: 1697625416297,  
“exp”: 1697629016297,  
“tokenExp”: 1697629016297  
}  
Still on onZoomSDKInitializeResult i am getting the response as :  
**onZoomSDKInitializeResult, errorCode=1, internalErrorCode=0**
