For the Search Directory Contacts api

https://api.qualtrics.com/c79e78a949572-search-directory-contacts

Is it possible to filter based on the value of an embedded data field?   The documentation above doesn’t appear to cover this(qualtrics newbie here), but I’m attempting to help someone replace an older api request that was doing this.   Example:   if I have an embedded field, XYZ, I want to filter on XYZ=’ABC”.

Thanks for your help.
