Define policy correctly

    return $user->id === $post->user_id;
}
2

Use authorization in controller

public function update(Request $request, Post $post)
{
    $this->authorize('update', $post);
    
    // or
    if ($request->user()->cannot('update', $post)) {
        abort(403);
    }

Check permissions in Blade

Blade
@can('update', $post)
    <a href="{{ route('posts.edit', $post) }}">Edit</a>
@endcan

@cannot('delete', $post)
    <p>You cannot delete this post</p>
@endcannot

Register policy in AuthServiceProvider

protected $policies = [
    Post::class => PostPolicy::class,
];
