Just realized that we can't change employee's role using REST API. Is this a bug or we need different API call?
curl --request POST \ --url 'https://sandbox.dev.clover.com/v3/merchants/WSXVX2XS45NCM/employees/VEDM3VSM65Y1J?access_token=xxxxx' \ --header 'content-type: application/json' \ --data '{"role":"EMPLOYEE","name":"Yangxue","pin":"444444"}'
