`wg set private-key` does not give any output with `wg show`

When running `wg set wg0 private-key <(wg genkey)`, no error is received but `wg show wg0` or `wg showconf wg0` does not show output for the `private-key` or the `public-key` (or maybe `own-public-key` is the public-key, but then it is not displayer in `wg`

Am I missing something or is there an issue ?

```
# no error reported when querying
$ socat - UNIX-CONNECT:/var/run/wireguard/wg0.sock
get=1
listen_port=49683

errno=0

# no error reported when setting key
# checked that `wg genkey output` is ok
$ wg set wg0 private-key <(wg genkey)
$
