Property [id] does not exist on this collection instance when trying to filter the data with ‘comment_id’

what i wants to do is to show the replies that are given to that particular comment on the post.Right now i am able to show the comment to that specific post but the replies are displayed along each comment.
here is the controller part of the code:

public function show($id)
    {
        $blog = Blog::findOrFail($id);
        $comments = Comment::where('blog_id', $id)->get()->all();
        $test = Comment::all();
//        $comments = Comment::whereIn('blog_id', $id)->get()->all();
        $commentReplies = CommentReply::where('comment_id'== $test->id)-
    >get();
//        $commentReplies = CommentReply::where('comment_id',$blog-
  >comment()->id)->get()->all();
        return 
view('admin/blog/front',compact('blog','comments','commentReplies'));
    }

i am saving the refrence to that comment in database in ‘comment_id’ but when i try to reach the ‘comment_id’ via $commentReplies it gives me the error of “Property [id] does not exist on this collection instance.“
