Remove or unpublish a case study

Hello team,

we have recently published the below case study on Drupal on the behalf of our company

https://www.drupal.org/case-study/building-loyalty-program-with-drupal

However, our client for whom we did this project wants it to be taken down for now, as it needs a review from them to ensure no information is shared which is not meant to be publicly available.

Can we please unpublish this post or remove it, till it is approved from the client's end to be shared on Drupal org or any other public platforms. This is very important for us.

Thanks
