CreateAction with form() how to use different model than the current one.

So I have a tasks table that lists different tasks and have actions that you can take on different resources. For example i have a task that it's "add track" and i have a form that creates tracks that i'm using in the manage tracks resource. I extracted it as a shared form and now i'm able to add it to this specific task as such:

Tables\Actions\Action::make('Add Track')
  ->form(TrackForm::schema())
  ->icon('iconoir-plus-circle')


When i click on the action button i get the following error
[object] (BadMethodCallException(code: 0): Call to undefined method App\Models\Task::trackArtists()

this is the track form schema:

class TrackForm
{

    public static function schema()
    {
        return [
            Forms\Components\TextInput::make('name')
                    ->columnSpan(2)
                    ->required(),
                Forms\Components\Repeater::make('trackArtists')
                    ->relationship()
                    ->hiddenLabel()
                    ->columnSpanFull()
                    ->columns([
                        'sm' => 4,
                    ])
                    ->schema([
                        Forms\Components\Select::make('artist_id')
                            ->relationship('artist', 'name')
                            ->getOptionLabelUsing(fn ($value): ?string => Artist::find($value)?->name)
                            ->searchable()
),
                    ];
    }
}


I understand the problem and it's that the form its thinking that it needs to use the model from the current resource which is "tasks"
I tried something like this:

Tables\Actions\Action::make('Add Track')
  ->model(Track::class)
  ->form(TrackForm::schema())
  ->icon('iconoir-plus-circle')


But not working.. am I missing something?

Is this possible to be able to tell the form on this action to use a different model?

Thanks
