To add a simple text input field to your Slack message, use the `SlackPlainTextInputBlock` class.
```php
use Symfony\Component\Notifier\Bridge\Slack\Block\SlackPlainTextInputBlock;
use Symfony\Component\Notifier\Bridge\Slack\SlackOptions;
use Symfony\Component\Notifier\Message\ChatMessage;

$chatMessage = new ChatMessage('Enter your feedback');

$options = (new SlackOptions())
->block(
new SlackPlainTextInputBlock('Your Feedback', 'feedback_action_id', 'Type your feedback here...')
);

// Add the custom options to the chat message and send the message
$chatMessage->options($options);

$chatter->send($chatMessage);
```
