[HELP] OGAds

Hi Guys,
I just signed in to OGAds and got accepted.
I understood that you dont get direct links there to promote. (promote via Content Locker)

Question:
How can i include the offers shown under "All Offers" into my content locker?
It seems like a content locker has its "own links" which can not be changed (in order to unlock t he locker).

So would be very nice if someone here could explain how this whole "promoting" works with the OGAds offers.
Thanks!
