Best way to view a PDF file in a new tab

Hi everyone,

I have a function that retrieve a base64 data, transform to pdf file and force download when I click in the pdf icon. How can I preview that pdf before download? And how can I change the name of the downloaded file?

Here is the table from invoice.blade.php

<table class="table table-hover table-responsive" id="tabla_documentos">
    <thead>
      <tr>
        <th scope="col">Tipo</th>
        <th scope="col">Cliente</th>
        <th scope="col">RUC/CI</th>
        <th scope="col">Estado</th>
        <th scope="col">Número</th>
        <th scope="col">Valor</th>
        <th scope="col">Fecha Emisión</th>
        <th scope="col">Fecha Autorización</th>
        <th scope="col">XML</th>
        <th scope="col">PDF</th>
      </tr>
    </thead>
    <tbody>
      @foreach($factura as $value)
      <tr>
        <td>{{ $value->id_documento }}</td>
        <td>{{ $value->persona_nombre }}</td>
        <td>{{ $value->ruc_cliente_proveedor }}</td>
        <td>{{ $value->estado }}</td>
        <td>{{ $value->numero_documento }}</td>
        <td>{{ $value->valor_total }}</td>
        <td>{{ $value->fecha_emision_documento }}</td>
        <td>{{ $value->fecha_autorizacion }}</td>
        <td><a href="{{ route('ruta.documentos.xml', $value->numero_autorizacion) }}" target="_blank"><i class="far fa-file-code fa-lg"></i></td>
        <!-- This is the PDF icon -->
        <td><a href="{{ route('ruta.documentos.pdf', $value->numero_autorizacion) }}" target="_blank"><i class="far fa-file-pdf fa-lg"></i></a></td>
      </tr>
      @endforeach
    </tbody>
  </table>

The PDF function from DocumentsController.php

public function pdf($id)
{
    $pdf = Emproservis::where('numero_autorizacion', $id)->firstOrFail();
    $base64 = $pdf->reporte_pdf;        
    $my_bytea = stream_get_contents($base64);  //This transform the bytea data to string. Is this ok?

    $decoded = base64_decode($my_bytea);
    $file = 'invoice.pdf'; //I want to name the file dynamically
    file_put_contents($file, $decoded);

    if (file_exists($file))
    {
        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        header('Content-Disposition: attachment; filename="'.basename($file).'"');
        header('Expires: 0');
        header('Cache-Control: must-revalidate');
        header('Pragma: public');
        header('Content-Length: ' . filesize($file));
        readfile($file);
        exit;
    }
}

And the web route from web.php

Route::get('/home/descargar/pdf/{id}', 'DocumentsController@pdf')
    ->name('ruta.documentos.pdf');
