How to transfer Extended Licence for a adobe stockimage to the customer?

I would like to transfer one Adobe stock image with an extended license to the customer, according to the Adobe guidelines. Adobe indicates that this is allowed in the extensive guidelines, but Adobe does not indicate how this should be done.

I would like to hear from Adobe itself or I will be called by an Adobe employee with knowledge of stock images and the extended license. Or will I receive a form that I can send so that the license transfer is arranged.

ps. I do not want to transfer my extended license to another email address or to another user. But I want to transfer a stock image according to the extended stock license.
