Entity mapping loaded in Symfony extension

[jkabat]

Im trying to update bundle from 2.7 => 3.3

In the old bundle Im loading appropriate entity mapping when particular extension is enabled.

    public function prepend(ContainerBuilder $container): void
    {
        if (!$this->isExtensionEnabled($container)) {
            return;
        }

        if (isset($container->getExtensions()['api_platform'])) {
            $container->prependExtensionConfig('api_platform', [
                'mapping' => [
                    'paths' => ['%kernel.project_dir%/config/api/resources/voice_twilio.yaml'],
                ],
            ]);
        }
    }

After upgrade I can only see automatically generated entity routes in "debug:routes" - all of them are starting by underscore.
Is it the loading of mapping done too late? What can I do in order to fix it? I'm not very well informed about the Symfony internals.

I have to admit, that upgrade is very confusing... actually that is the reason, why I have waited so long with it...
