Question Cougar QBX - How to install optical disk drive?

[Kilili]

The Cougar case has some clips and screws for installing a slot loading ODD, but no info on how to use them. I am mystified. Do you know how to do the install without just taping the drive down?

It sits behind the PSU at the front of the case and clips to the removable bay cage (where you can also mount HDDs and SSDs)

Rather, it sits in front of the PSU in the removable drive cage. I understand all that, and how to position the ODD in the cage. What I do not understand is how to use the clips to keep the ODD in position. The manual has no info of relevance, other than to identify the clips themselves.
