How can I totally stop my video files downloadable from my laravel 8 website project? - laravel-8

Question

I have a Laravel 8 web project which need to stop downloading video files from my website. I need a function which will totally stop download & will say "The requested file doesn't exist" if the video file link input on IDM or at others downloader softwares. Tell me how can I stop?
View page & Controller code:
<video oncontextmenu="return false;" src="{{asset('uploads/drama-movie-video/trailers/'. $video->trailer)}}" controls controlsList="nodownload" width="250px" height="250px" poster="{{asset('images/profile1.jpg')}}">
</video>
**My video controller:**
public function show($id) {
//views count
$oldviews = Video_views::where('video_id', $id)->value('amount');
$newviews = $oldviews + 1 ;
$updateviews = Video_views::where('video_id', $id)
->update(['amount' => $newviews]);
//seen count
$visitor = request()->ip();
$searchvisitorip = Video_seen::where('video_id', $id)->where('visitor_ip', $visitor)->value('id');
if ($searchvisitorip < 1) {
$seen = new Video_seen;
$seen->video_id = $id;
$seen->visitor_ip = $visitor;
$seen->save();
}
$video = Video::find($id);
$user = Auth::User()->id;
$queryviewer= Viewer::where('video_id', $video->id)->where('viewer_id', $user)->value('viewer_id');
return view('frontend.pages.video.video.show', compact('video', 'queryviewer', 'user', 'newviews'));
}
