Zoom Windows SDK onAuthenticationReturn not trigerring

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…
