Validate a field inside a modal

I'd like to know if there is a way to validate a field inside a modal window. (which is of course called from an action).
I have a Select field that has to be filled in, before executing the action. How can I achieve this?

This is my code so far:

Action::make('generate')
  ->link()
  ->slideOver()
  ->icon('heroicon-o-sparkles')
  ->modalWidth('3xl')
  ->modalHeading('Generate')
  ->modalSubmitActionLabel('Save')
  ->closeModalByClickingAway(false)
  ->form([
      Select::make('prompt')
          ->label('Prompt')
          ->required()
          ->reactive()
          ->searchable()
          ->preload()
          ->options(Prompt::all()->pluck('name', 'id')),
  
      RichEditor::make('job_description_original')
          ->disableAllToolbarButtons()
          ->label('Origineel')
          ->default(fn ($livewire) => $livewire->data['job_description']),
      Actions::make([
          Action::make('generate_alternative')
              ->label('Generate')
              ->action(function ($get, $set, $record, $livewire) {

                  // MAKE SURE THERE IS A PROMPT SELECTED?
  
                  $result = GenerateSummary::make()->handle(
                      $get('prompt'),
                      $record->job_title,
                      $get('job_description_original')
                  );
  
                  $set('job_description_alt', $result);
              }),
      ]),
      RichEditor::make('job_description_alt')
          ->disableAllToolbarButtons()
          ->hiddenLabel(),
  ])
  ->action(function (array $data, $set): void {
      $set('job_description', $data['job_description_alt']);
  }),
