CAS5.3.x, How to get refresh token in authorization code flow?

[Yan Zhou]

Hello,

I am able to get access token through /token endpoint, but I do not see a way to get both refresh token and access token.

This is the response of CAS5 /token endpoint. I do not see refresh token there.  How do I get refresh token, either separately or get it returned along with access token?

Thx!
