No expire time in refresh token

Hi experts,

I’m using key cloak 22 version in my Web and mobile application. In Webapp I am getting one refresh token which has expire time. But in mobile I am getting the refresh token without expire time.

have enclosed the decoded version of the refresh token.

kindly help me on this, experts
thanks

This is not a pure refresh token, this is an offline token ("typ": "Offline").
The authentication was initiated with the offline_access scope (see scope claim in token).
