Symfony Bundle not creating bundle-configuration yaml file in project - symfony

Question

A so far working bundle now needs its own configuration file inside the projects using the bundle, to manage bundle settings individually.
However, no matter which approach I use (the old one before Symfony 6.1 nor the new one extending AbstractBundle) there is - at no time - any new .yaml-File created inside the projects ./config/packages/ directory.
This is my code (the old style, prior to Symfony 6.1, extending Bundle):
Bundle Class
mycorpforms/src/MyCorpFormsBundle.php
<?php
namespace MyCorp\FormsBundle;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\Config\Definition\Configurator\DefinitionConfigurator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\ExtensionInterface;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\HttpKernel\Bundle\Bundle;
class MyCorpFormsBundle extends Bundle
{
// empty
}
Configuration
mycorpforms/src/DependencyInjection/Configuration.php
<?php
namespace MyCorp\FormsBundle\DependencyInjection;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;
class Configuration implements ConfigurationInterface
{
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder('mycorp_forms');
$treeBuilder->getRootNode()
->children()
->booleanNode('favorite_submenu_enabled')->defaultFalse()->end()
->end()
;
return $treeBuilder;
}
}
Extension
mycorpforms/src/DependencyInjection/MyCorpFormsExtension.php
<?php
namespace MyCorp\FormsBundle\DependencyInjection;
use Knp\Bundle\SnappyBundle\DependencyInjection\Configuration;
use Symfony\Component\Config\Definition\Processor;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;
class MyCorpFormsExtension extends Extension
{
public function load(array $configs, ContainerBuilder $containerBuilder)
{
$loader = new YamlFileLoader(
$containerBuilder,
new FileLocator(__DIR__.'/../../config/packages')
);
$loader->load('mycorp_forms.yaml');
$configuration = new Configuration();
$processor = new Processor();
$config = $processor->processConfiguration($configuration, $configs);
$containerBuilder->setParameter('mycorp_forms.favorite_submenu_enabled', $config['favorite_submenu_enabled']);
}
}
Yaml
Additionally I added the desired mycorp_forms.yaml inside the bundles ./config/packages/ dir.
This is the actual file required in the projects:
mycorpforms/config/packages/mycorp_forms.yaml
mycorp_forms:
# Enable Favorite-Sub-Menu (Requires Knp-Snappy-Bundle !)
favorite_submenu_enabled: false
The bundle installs flawlessly in any of my projects, however no mycorp_forms.yaml file is created. Obviously this requires symfony/flex which is so far required by the bundle itself.
Q: What do I miss here?
Q: How can this yaml-file automatically be added when the bundle is installed?
I read the documentation up and down numerous times, but to be honest, I get more confused every time.
Thank you very much for any help or explanation!

This requires Symfony Flex
To have a .yaml config file being generated/updated automatically, there is 2 possible ways:
public bundle: register it in the public recipe repository
private bundle: set up your own private flex recipe repository
