is it possible to get value from parent form with form action modal?

Refer to https://filamentphp.com/docs/3.x/forms/fields/builder#using-get-to-access-parent-field-values

I try with
$form   // *main form
  ->schema
    TextInput::make('first_form_value')
    Forms\Components\Actions([ 
      Forms\Components\Actions\Action::make()  // *second form
        ->form([
          Forms\Components\Actions([
            Forms\Components\Actions\Action::make() // *third form
              ->form([
                 TextInput::make('third_form_value')
              ])
              ->action([ fn(Get $get,Set $set)=>self::setValue($get,$set) ])  // *set main  form value
          ])
        ])
        ->action([
        ])
    ])

on action that I said set main form value I calling Get,Set and push trough self::function

on self::function I try to get value from third form and set value to first form with

$get('third_form_value')
$set('../../../first_form_value')


but the result is when $get('third_form_value') it's show null
then I try $get() it's show value from second form
I try $get('../') it's show value of second form and third form
and either I try ../../ ../../../ or else it's always show null

how can I access value correctly on main , second and third form?
