How to attach and detach a relation in case there were values

My resource may has One to One (Polymorphic) relationship with Review, I want to create a review if I wrote values and if it was null want to delete it if existed

Forms\Components\Fieldset::make(__('Booking review'))
  //create only if there are values, if null delete
  ->relationship('review')
  ->schema([
      Forms\Components\TextInput::make('rating')
          ->requiredWith('comment'),
      Forms\Components\Textarea::make('comment')
          ->columnSpan(2),
  ])
  ->visibleOn('edit')
  ->visible(function (Forms\Get $get): bool {
      return $get('status') === 'in review';
  }),

Forms\Components\Fieldset::make(__('Booking review'))
  //create only if there are values, if null delete
  ->relationship('review')
  ->schema([
      Forms\Components\TextInput::make('rating')
          ->requiredWith('comment'),
      Forms\Components\Textarea::make('comment')
          ->columnSpan(2),
  ])
  ->visibleOn('edit')
  ->visible(function (Forms\Get $get): bool {
      return $get('status') === 'in review';
  }),
