How to get another refresh token

I have a problem. I got authorization_code after oauth. Send it to got jwt token with refresh token, when the main token will expired. When the jwt token had expired i send another request with the refresh token, and got another jwt token, but how can i get another refresh token too, to request another token latter?

You can keep using the same refresh token indefinitely. It doesn’t time out. Unless the user revokes access from their profile, the refresh token is good as long as your client needs access tokens.
