**Zoom Windows SDK onAuthenticationReturn not triggering**

I tried to call the below lines  
ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetAuthServiceWrap().Add\_CB\_onAuthenticationReturn(onAuthenticationReturn);  
ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetAuthServiceWrap().Add\_CB\_onLoginRet(onLoginRet);  
ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetAuthServiceWrap().Add\_CB\_onLogout(onLogout);  
//  
ZOOM\_SDK\_DOTNET\_WRAP.AuthContext param = new ZOOM\_SDK\_DOTNET\_WRAP.AuthContext();  
param.jwt\_token = textBox\_apptoken.Text;

```
     ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance.GetAuthServiceWrap().SDKAuth(param);
       Hide();

```

But onAuthenticationReturn method not getting called. I tried to set jwt\_token from App Credentials. The MainWindows.xml window is just hiding after Auth button clicked…
