Select::make('slot')
    ->prefixIcon(fn (Get $get, ?Model $record) => 
          (new Appointment())->getAvailableTimes($get('date')) != null ? 'heroicon-o-check' : "heroicon-o-x-mark"
      )
    ->prefixIconColor(fn (Get $get, ?Model $record) => 
          (new Appointment())->getAvailableTimes($get('date')) != null ? 'primary' : "gray"
      )
    ->disabled(fn (Get $get, ?Model $record) => 
          (new Appointment())->getAvailableTimes($get('date')) != null ?
      )
    ->options(fn (Get $get, ?Model $record) =>
