Relationship Manager AttachAction custom form

Hi all,
I try to attach Employee model to Training Model. In the table employee_tainings there is a required training_session_id. I would like to modify the AttachAction form to have another field so that user can select training session before submiting. However, No matter I try to change form() in configurationAttachAction(), it won't affect . Please advise how I would do this.

    protected function configureAttachAction(Tables\Actions\AttachAction $action): void
    {
        $action
            ->authorize(static fn(RelationManager $livewire): bool => (! $livewire->isReadOnly()) && $livewire->canAttach())
            ->form(static fn(Form $form) => $form->schema([
                Forms\Components\TextInput::make('full_name')
                    ->required()
                    ->maxLength(255),
                Forms\Components\Select::make('training_session_id')
                    ->options(
                        \App\Models\TrainingSession::all()->pluck('name', 'id')
                    )
            ]))
            ->attachAnother(false);
    }

Solution
I just found that I could not do it from function configureAttachAction, but it works on header action extensiion itself.
$table->headerActions([
                Tables\Actions\AttachAction::make()
                    ->form(fn(AttachAction $action): array => [
                        $action->getRecordSelect(),
                        Forms\Components\Select::make('training_session_id')
                            ->options(
                                \App\Models\TrainingSession::where('training_id', $this->getOwnerRecord()->id)->pluck('name', 'id')
                            )
                    ])
                    ->action(
                        function (array $arguments, array $data, Form $form, Table $table, AttachAction  $action): void {
                            $this->doAttach($arguments, $data, $form, $table, $action);
                        }
                    )
                    ->attachAnother(false),
            ])
