It actually works, see [1]:

The name of a standby server for this purpose is the application_name
setting of the standby, as set in the standby's connection
information. In case of a physical replication standby, this should be
set in the primary_conninfo setting in recovery.conf; the default is
walreceiver. For logical replication, this can be set in the connection
information of the subscription, and it defaults to the subscription
name.
