How to view pdf file in laravel blade?

Hi, I'm building a website where has a career page. On that page one user can apply for a single job application by uploading a pdf file. I stored data in this way

		 $file = $request->cv;
        if ($file) {
            $file_name = hexdec(uniqid());
            $ext       = strtolower($file->getClientOriginalExtension());

            $file_full_name = $file_name . '.' . $ext;
            $upload_path    = 'files/';
            $upload_path1   = 'backend/files/';
            $file_url       = $upload_path . $file_full_name;
            $success        = $file->move($upload_path1, $file_full_name);
        }
        $job = Applicant::create([
            'name'    => $request->name,
            'contact' => $request->contact,
            'email'   => $request->email,
            'cv'      => $file_url,
        ]);

and it's stored perfectly. I want to preview this uploaded pdf file into admin panel. I tried toinstall this package https://github.com/webVenus928/pdf-viewer-Laravel . but it threw this error [Symfony\Component\Debug\Exception\FatalThrowableError] Class 'Goodnesskay\LaravelPdfViewer\LaravelPdfViewerServiceProvider' not found

Can anyone tell me how can I preview pdf file into blade?
