here is controller method controller fetches user and sends email

public function __invoke(Request $request)
{
   try{
        $user = User::all()->first();
            
            if($user->language == 'enUS'){
                $emailTemplate = email_template::whereType('information_en')->first();   
            }else if($user->language == 'deDE'){
                $emailTemplate = email_template::whereType('information_de')->first();
            }
            $templateBody = $emailTemplate->body;
            $templateBody = str_replace('#Title#',  $user->title, $templateBody);
            $templateBody = str_replace('#LastName#', $user->lname, $templateBody);

            $data = [];
            $data['email'] = $user->email;
