Error: Failed to add/activate new connection: Not authorized to control networking.

Hi, I'm getting Error: Failed to add/activate new connection: Not authorized to control networking. when testing your sample code.

Here is my php file:

<?php

error_reporting(E_ALL);
ini_set('display_errors', 1);

include __DIR__ . '/phpwifi/vendor/autoload.php';

use Sanchescom\WiFi\WiFi;

class Example
{
    public $device;

    /**
     * @throws Exception
     */
    public function getAllNetworks()
    {
        $networks = WiFi::scan()->getAll();
        foreach ($networks as $network) {
            echo $network . "<br>";
        }
    }

    /**
     * @param $ssid
     * @param $password
     */
    public function connect($ssid, $password)
    {
        try {
            WiFi::scan()->getBySsid($ssid)->connect($password, $this->device);
        } catch (Exception $exception) {
            echo $exception->getMessage();
        }
    }

    /**
     * @throws Exception
     */
    public function disconnect()
    {
        $networks = WiFi::scan()->getConnected();

        foreach ($networks as $network) {
            $network->disconnect($this->device);
        }
    }
}

$example = new Example();
try {
    $example->device = 'wlan0';
    $example->getAllNetworks();
    $example->connect('MY-SSID-NAME', 'MY-SSID-PASSWORD');
    // $example->disconnect();
    } catch (Exception $e) {
    //
    }

?>

Here is the output of the when running the php file:

F4:09:D8:AA:BD:7F|MY-SSID-1|358|79|WPA2|(none) pair_ccmp group_ccmp psk|2412|true
E4:CA:12:DB:0D:94|MY-SSID-2|268|34|WPA1 WPA2|pair_tkip pair_ccmp group_tkip psk pair_tkip pair_ccmp group_tkip psk|2462|false
Command "LANG=C nmcli -w 10 device wifi connect "MY-SSID-2" password "MY-SSID-PASSWORD" ifname "wlan0" 2>&1" exited with code 4: Error: Failed to add/activate new connection: Not authorized to control networking.

Any idea what went wrong? Running the wifi list and the connect command via console went well, no error.
