NO_OP
Set this linker in the UserCreationOptions supplied to createUser to create an unlinked user.
If you wish to link this user at a later time, you can use either one of linkUser, linkUser, or linkUser. However, note that linking a user after its creation has certain limitations (see the below note).
Note: An unlinked Sentiance user cannot be linked to an app user that already exists on the Sentiance Platform (i.e. with an app user identifier that you already supplied to Sentiance during a past linking request). You can only link to an app user that is new to Sentiance. This is because an existing app user will already have a corresponding Sentiance user on the platform, and that Sentiance user cannot be restored here anymore. To restore that user, you must reset the SDK and recreate a linked Sentiance user instead.
