[TYPO3-mvc] setHidden - how to add record as hidden

[Dawid Pacholczyk]

Hello Listm,
  I want to ask is there a method that allows me to add new record to db 
as hidden ?
I want to add an inactive record (so it will be seen in BE but not on 
FE) and I want to active it after clicking on url in email.

How can I do that ? Do I need to do some special query in repository 
that will edit last record ?

Best regards,
Dawid Pacholczyk
