Get an array of all ids with whom there were dialogues in the community (vk api)?

Question

PHP

Hello everyone, there is such a method https://vk.com/dev/messages.searchConversations
I need to one-time add everyone who has ever written to the bot in the database, exactly their id
How can this be implemented? I practically did not work with vk-api, maybe someone has a ready-made solution for my question?

<?php

$data = [
    'access_token' => 'ключ_доступа_сообщества',
    'v' => 5.95
];

$url = 'https://api.vk.com/method/messages.getConversations?' . http_build_query($data);
$data = file_get_contents($url);
$json = json_decode($data, true);

$users = [];
foreach ($json['response']['items'] as $item) {
    $userId = $item['conversation']['peer']['id'];

    $users[] = $userId;
}

print_r($users, true);
