use Symfony\Component\Notifier\Bridge\Slack\Block\SlackSectionBlock;
use Symfony\Component\Notifier\Bridge\Slack\SlackOptions;
use Symfony\Component\Notifier\Message\ChatMessage;

$chatMessage = new ChatMessage('Contribute To Symfony');

// Create Slack Actions Block and add some buttons
$contributeToSymfonyBlocks = (new SlackActionsBlock())
    ->button(
        'Improve Documentation',
        'https://symfony.com/doc/current/contributing/documentation/standards.html',
        'primary'
    )
    ->button(
        'Report bugs',
        'https://symfony.com/doc/current/contributing/code/bugs.html',
        'danger'
    );

$slackOptions = (new SlackOptions())
    ->block((new SlackSectionBlock())
        ->text('The Symfony Community')
        ->accessory(
            new SlackImageBlockElement(
                'https://symfony.com/favicons/apple-touch-icon.png',
                'Symfony'
            )
        )
    )
    ->block(new SlackDividerBlock())
    ->block($contributeToSymfonyBlocks);

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

$chatter->send($chatMessage);

        use Symfony\Component\Notifier\Bridge\Slack\Block\SlackDividerBlock;
use Symfony\Component\Notifier\Bridge\Slack\Block\SlackSectionBlock;
use Symfony\Component\Notifier\Bridge\Slack\SlackOptions;
use Symfony\Component\Notifier\Message\ChatMessage;

$chatMessage = new ChatMessage('Symfony Feature');

$options = (new SlackOptions())
    ->block((new SlackSectionBlock())->text('My message'))
    ->block(new SlackDividerBlock())
    ->block(
        (new SlackSectionBlock())
            ->field('*Max Rating*')
            ->field('5.0')
            ->field('*Min Rating*')
