Maybe this will help. Mosyle has a popup too explaining where to generate more JWTs:

API Integration
Ability to create more than one API token integration. New tokens will be created automatically with JWT Authentication. (My School > Integrations > API Integration)

Unfortunately when we apply the token to iiQ, we get an error message: ...no access token has been configured or it is invalid. [ Value cannot be null. (Parameter 's') ].
