How to view Wi-Fi passwords in plain text from the command line in Ubuntu 23.10? [closed]

I'm connected to internet over ethernet but have saved wifi passwords.

The folder /etc/NetworkManager/system-connections is empty.

This command shows nothing (replace variable with desired uuid):

# nmcli -s -g 802-11-wireless-security.psk connection show $UUID

this doesn't help either:

# for uuid in $(nmcli -g UUID connection show); do    nmcli -g 802-11-wireless.ssid,802-11-wireless-security.psk connection show $uuid | awk -F: '{        if (NR == 1) printf "SSID: %s\n", $0;        if (NR == 2) printf "Password: %s\n\n", $0;    }'done

The output of that code:

SSID: Home_WiFiPassword: <hidden>SSID: Starbucks_clientsPassword: <hidden>SSID: Sony_phone_hotspotPassword: <hidden>

Any help to get the passwords in plain text? They are stored somewhere because the wifi reconnects and auths automatically, no need to re-enter the password.

--updated--

These are the commands suggested by @Raffa with small modifications:

# nmcli dev wifi show-passwordError: No Wi-Fi device found.

# for conn in $(nmcli -t -f NAME con show); do     echo "Details for $conn:";     sudo nmcli connection show "$conn" --show-secrets | grep 802-11-wireless-security.psk; doneDetails for Wired:Error: Wired - no such connection profile.Details for connection:Error: connection - no such connection profile.Details for 1:Error: 1 - no such connection profile.Details for lo:Details for virbr0:Details for Home_WiFi:802-11-wireless-security.psk:           --802-11-wireless-security.psk-flags:     1 (agent-owned)Details for Starbucks_clients:802-11-wireless-security.psk:           --802-11-wireless-security.psk-flags:     1 (agent-owned)Details for Sony_phone_hotspot:802-11-wireless-security.psk:           password1802-11-wireless-security.psk-flags:     0 (none)

Now some networks display the password and others don't.
