getting custom user feeds

[pishguy]

is any way to get custom user feeds instead of logged user? for example:

Route::get('/instagram', function () {
    $username = 'zzzzz';
    $password = 'zzzzz';
    $instagram  = Instagram::withCredentials(
        new \GuzzleHttp\Client(),
        $username,
        $password,
        new Psr16Adapter('Files')
    );
    try{
        $instagram->login();

        dd($instagram->getFeed('CUSTOM USER'));

    } catch (InstagramException $ex) {
    dd( $ex->getMessage()) ;
}
