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

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”

Is everything fine? Or I miss something?
