[`var groupHandle: RCSHandle.Group`](/documentation/TelephonyMessagingKit/RCSService/ChangeGroupChatSubjectRequest/groupHandle)

[`var newSubject: String`](/documentation/TelephonyMessagingKit/RCSService/ChangeGroupChatSubjectRequest/newSubject)

### Supporting RCS encryption

[`var isEndToEndEncrypted: Bool`](/documentation/TelephonyMessagingKit/RCSService/ChangeGroupChatSubjectRequest/isEndToEndEncrypted)
