Need help to understand point-in-time recovery in Mongodb Atlas

HI Team,
when i am trying to restore deleted data in Mongodb Atlas by using oplog timestamp i am getting below warning. does it mean data will be deleted permanently from selected cluster??

warning massage:-All existing data on the target cluster ABC will be deleted prior to the restore! The cluster ABC will be unavailable for the duration of the restore. Type “I Agree” to perform restore.
