How do you correctly use @can in blade templates using policies

I'm not able to make the @can() in a blade template as the documentation suggest

Here's my policy:

public function update(User $user, Canal $canal): bool {
  return ($canal->user->id == $user->id) and ($user->hasPermissionTo('actualizar canal'));
}

I'm using Spatie Permissions. Anyway, this policy works, if I protect the routes in the controller as:

  public function edit(Request $request, Canal $canal) {
    $this->authorize('update', $canal);
    return view('Canal/edit', ['canal' => $canal]);
  }

Now, my problem is with the blade. I want to conditionally render a button to edit the $canal, I'm trying this:

  @can('update', App\Models\Canal::class)
    <x-gui.link-button href="{{ route('canal.edit', $canal->id) }}" value="Modificar" />
  @endcan

This is exactly as the docs say. But I'm getting an error, it says it needs another parameter in the call:

Too few arguments to function App\Policies\CanalPolicy::update()

So I'm guessing I have to send the user also in the @can(), I change it to:

  @can('update', Auth::user(), App\Models\Canal::class)
    <x-gui.link-button href="{{ route('canal.edit', $canal->id) }}" value="Modificar" />
  @endcan

This doesn't work either, this simply doesn't "call" the policy. How do I know? I placed some Log::info() there.

Any idea?

To fix this, send the $code instead of App\Models\Canal::class on the 2nd param of @can like:

@can('update', $canal)
    <x-gui.link-button href="{{ route('canal.edit', $canal->id) }}" value="Modificar" />
@endcan
