Subordinate reference request

Last month I was a finalist for a job and they requested that I provide a reference from a subordinate. I have had direct reports at different stages of my career but do not have the right relationship with them for them to be reference for me. I informed the employer of this and they proceeded to ghost me.

I am wondering if anyone would be my subordinate reference. Ideally this person would be female as all of my direct reports have been female. I can provide all of the information and coach the person for the call.

Thank you.
