Creating multiple sessions with login for one of them

[dmdbs]

Good time of day.
I've been struggling for the third day now, but the documentation is too complicated for me.
Maybe you can tell me what to do, or show me a real example.
I want to make it possible to log in from multiple Telegram users. Let's say there are 100 accounts, and the session of each of them takes up the minimum amount of memory. And then authorize the session for any of these accounts. Performing further operations should not cause me problems.

The most difficult thing for me is saving sessions, fetching and using.
I'm stupid and that's all I've come to, but in this case I don't even understand what I've come to.
$database = (new Mysql)
->setUri($host)
->setUsername($username)
->setPassword($password)
->setDatabase($db)
->setEnableFileReferenceDb(false)
->setEnableMinDb(false)
->setEnableFullPeerDb(false)
->setEnablePeerInfoDb(false)
->setEnableUsernameDb(false);
$auth = (new Auth)
->setDefaultTempAuthKeyExpiresIn(3600);
$settings = (new Settings())
->setDb($database)
->setSerialization((new Serialization())->setInterval(300))
->setAppInfo((new AppInfo)->setApiId($apiID)->setApiHash($apiHash))
->setAuth($auth);
$MadelineProto = new API('session.madeline', $settings);
$MadelineProto->updateSettings($settings);
$MadelineProto->start();

After spending a whole week, I found a solution without a database, generating folders with files for each user

Whoops sorry missed this thread, you just have to change the session name, I thought it was obvious from the documentation, if it isn't feel free to submit a clarification!
