List all Schedule Query with user who created

I use bq ls --transfer_config --transfer_location=asia-southeast-1 --format json without max-results to list all the schedule query existing. It should returns ListTransferConfigsResponse having TransferConfig Obj inside but it's not. I need "OwnerInfo" which has the email of the user. Did google write missing docs? I want to call 1 api to get all info. Any help?
