Refresh Token is Missing

[caktoy]

I tried follow every step and then try to access {my_url}/oauth/token with body application/json like this:

{
	"grant_type": "client_credentials",
	"client_id": "1",
	"client_secret": "Dq5E8lfuPel1Ym33qqt9Yy5wIRe4NGzOVNsYhZQP"
}

But the response only contains token_type, expires_in, and access_token without refresh_token attribute. Is there something step I need to do. Please help.
