Is there a way I can fix one side conversation in LARAVEL chatbot?

Following is the code. where in user is welcomed. its ID is verified and name & class is fetched from db. After class selection selected class displayed on same side rather I want it to display on right.

public function getUser(){

    $user = DB::table('users')->where('uid','=',20230005210)->first();
    
    
    if(!empty($user)){
        $this->say("Hi " . $user->name . " ( ID:". $user->uid .")...");
        $this->say("Welcome ENO!!");
        $this->couSelect($user->class);
        $this->couSelect($user->class);
        session(['uid' => $user->uid]);
        session(['class' => $user->class]);
    }else{
     
        $this->say("Sorry, Not Verified");
    }
}

public function getUserData(){

    $userData= new stdClass;
    $this->ask("Enter ID",function(Answer $answer)use ($userData){
        $this->name = $answer->getText();
            

            $this->selectClass();

            
        });
  
}

public function verifyUser($userdata){
   
    $moodleData =Http::post("http://localhost/......=". $userdata->name)->json();
    
    if(!empty($moodleData["users"])){
        $m_username = $moodleData["users"][0]["username"];
        $m_firstname = $moodleData["users"][0]["firstname"];
        $m_fullname = $moodleData["users"][0]["fullname"];
        $this->curr_username = $m_username;
        $this->curr_userclass = $userdata->class;


        $this->say("Hi.. " . $m_firstname . " (User ID:". $m_username .")...");
    
        $this->say("Welcome!!");
       
        $this->courseSelect( $this->curr_userclass);
        session(['uid' =>  $this->curr_username]);
        session(['class' => $this->curr_userclass]);
    }else{
        
        $this->say("Sorry, Not Verified");
    }

}

public function getUserID(){
    $user = DB::table('students')->where('uid','=',2022005332)->first();
    return $user->id;
}

public function selectClass(){

    $question = Question::create('Select Class')
                ->callbackId('class_select')
                ->addButtons([

                    Button::create('VI')->value('VI'),
                ]);

    $this->ask($question, function(Answer $answer) {
            
      
            if ($answer->isInteractiveMessageReply()) {

                    $this->chapterSelect($this->selectedCourseID, 7, 12);
                
                }else{
            }
        }

    });
}`

Initially the conversation looks sender and receiver.
Later it comes on one side only

Plz help.
