Add user storage in User Federation

Hi All,

I am able to add provider through UI but I need help to add through CLI due to automation.

I am using REDHat SSO 7.1 and when tried to execute cmd

              kcadm.bat create user-federation/instances -r Test4 -s providerName=my-provider -s priority=0 -s config.debug=false

Resource not found for url: http://localhost:8080/auth/admin/realms/Test4/user-federation/instances

Is there any Json that I can execute?
