How to recreate a nested Eloquent Collection in Laravel 9? - laravel-blade

Question

I would like to re-use a Laravel 9 Blade template that I built to display the results of an Eloquent query. But this time I want to fill it with data from an API, so I need to re-create the structure of the Collection to match the Blade template.
Possible solutions:
1. Manually recreate the Collection with the same structure:
$author1 = ["name" => "John Smith"];
$author2 = ["name" => "Larry White"];
$authors = Collect([$author1, $author2]);
$library1 = ["title" => "City library", "authors" => $authors];
$libraries = Collect([$library1]);
return view('library', compact('libraries'));
2. Recreate the Collection using existing model and its relationships:
$author1 = new Author;
$author1->name = "John Smith";
$author2 = new Author;
$author2->name = "Larry White";
$library1 = new Library;
$library1->title = "City library";
$library1->authors->push($author1);
$library1->authors->push($author2);
$libraries = [$library1];
return view('library', compact('libraries'));
Both options don't work and throw error: "name" is not defined on $author->name
library.blade.php:
#forelse ($libraries as $library)
<h1>{{ $library->title }}</h1>
<ul>
#forelse ($library->authors as $author)
<li>{{ $author->name}}</li>
#endforelse
</ul>
#endforelse
