怎么修改ThinkPHP6中的Session配置

return [
    // session name
    'name'           => 'think_session',
    // session auto start
    'auto_start'     => true,
    // session type
    'type'           => '',
    // expire time
    'expire'         => 86400,
    // use database
    'use_database'   => false,
    // data compression
    'data_compress'  => false,
    // cache prefix
    'prefix'         => '',
    // cache expire time
    'cache_expire'   => null,
    // session id
    'id'             => '',
    // session path
    'path'           => '',
    // session domain
    'domain'         => '',
    // session secure
    'secure'         => false,
    // session httponly
    'httponly'       => false,
    // session redis connection
    'redis_connection' => 'session_redis',
    // redis handler
    'redis_handler'  => '',
    // redis session key prefix
    'redis_prefix'   => '',
];

$request = Request::instance();
$session = $request->session();
$value   = $session->get('key');

$request = Request::instance();
$session = $request->session();
$session->set('key', 'value');
