How to Override an Annotation Entity in Akeneo

[jkrajpootbdn94]

Akeneo Version: 3.x

Description: I am currently working on customizing Akeneo and would like to override an annotation-based entity in Akeneo. Specifically, I am trying to extend and modify the ConfigValue entity from Oro\Bundle\ConfigBundle.
Objective:
To replace the default ConfigValue entity with a custom version that adds additional functionality, without modifying the vendor files.

Steps Taken:

1. Created a new entity class (ExtendedConfigValue) in my custom bundle that extends the original ConfigValue entity.

2. Configured resolve_target_entities in my Resources/config/config.yml file to point from Oro\Bundle\ConfigBundle\Entity\ConfigValue to My\Bundle\Entity\ExtendedConfigValue.

doctrine:
    orm:
        resolve_target_entities:
            Oro\Bundle\ConfigBundle\Entity\ConfigValue: My\Bundle\Entity\ExtendedConfigValue

3. Cleared the Symfony cache and ran doctrine:schema:update to ensure schema changes apply.

Issue:
Despite these steps, the application continues to reference the original ConfigValue entity, and I encounter errors indicating that it does not recognize the new configuration.

Questions:

1. Is there any additional configuration required to override an annotation-based entity in Akeneo?
2. Are there specific Akeneo or Symfony caching steps I might have missed that could prevent the override from taking effect?
3. If anyone has successfully implemented an annotation-based entity override in Akeneo, could you share the steps or configurations that worked?

Thank you for any guidance you can provide!
