Cannot restore volume to a different availability zone

cinderclient added support in Wallaby[1] to be able to restore a backup to a different AZ with the help of --availability-zone and --volume-type parameters
However, openstackclient doesn't have such support

# cinderclient

$ cinder backup-restore
usage: cinder backup-restore [--volume <volume>] [--name <name>] [--volume-type <volume-type>] [--availability-zone <AZ>] <backup>
error: the following arguments are required: <backup>
Try 'cinder help backup-restore' for more information.

# openstackclient

$ openstack volume backup restore
usage: openstack volume backup restore [-h] [-f {json,shell,table,value,yaml}] [-c COLUMN] [--noindent] [--prefix PREFIX] [--max-width <integer>] [--fit-width] [--print-empty] [--force] <backup> [<volume>]
openstack volume backup restore: error: the following arguments are required: <backup>
