How can I access Parent Record for Unique validation on Relation Manager

How Can I acces parent Model inside the unique validation closure.

I need to check if the record is unique for Parent Record. Not the entire table

After searching in the docs. Found this

TextInput::make('name')
                            ->label('Region Name')
                            ->required()
                            ->reactive()
                            ->unique(static::getResource()::getModel(), 'name', function ($record) {
                                return $record;
                            }, function (Unique $rule, $record = null,$livewire) {
                                
                                return $rule
                                    ->when($record, function ($query, $record) {
                                        return $query->where('data_center_id', $record->data_center_id);
                                    },function($query) use ($livewire){
                                        return $query->where('data_center_id', $livewire->ownerRecord->id);
                                    });
                            })
                            ->validationAttribute('Region Name')
                            ->rules([
                                'string',
                                'max:300',
                            ])
