Is possible to refresh offline_token affer SSO Max reached?

I’m trying to use offline_tokens, but after SSO Session Max is reached, the access token is not active anymore in introspect api validation, and if do a refresh_token the expires_in get a negative value. like this:

{
    "access_token": "eyJhbGciOiJ...",
    "expires_in": -168,
    "id_token": "eyJhbGciOiJ...",
    "not-before-policy": 1596032378,
    "refresh_expires_in": 0,
    "refresh_token": "eyJhbGciOiJ...",
    "scope": "openid offline_access",
    "session_state": "c2be2f50-bc10-4985...",
    "token_type": "bearer"
}

According to the documentation, the offline token should be valid even if SSO Max was reached. The introspect don’t validate offline token?

Thank you
