expireAt property
final
DateTime of this RefreshToken expiration.
Once expired, it's not usable anymore and a new Session should be renewed to get a new RefreshToken.
Client applications are supposed to use this field for tracking RefreshToken's expiration and sign out MyUsers properly.
Expiration of a RefreshToken is not prolonged on refreshing, and remains the same for all the RefreshTokens obtained.
Implementation
final PreciseDateTime expireAt;
