iOS SDK JWT key not working

Meeting SDK iOS
6

This part works fine. JWT doesn’t (((
I’m sure I’m not correct generate JWT:

I use clientKey&clientSecret to generate JWT in JWT io

  1. Set clientKey in “appKey”
  2. Set Unix current timestamp (1582729214) to “iat”
  3. Set Unix current timestamp + expiration timestamp (1582739214) to “exp”
  4. Set expiration time (60) to “tokenExp”
  5. Set clientSecret in “your-256-bit-secret”

After I take generated jwt and put in authService?.jwtToken parameter.

Is everything fine? Or I miss something?
