Hey, I just made a Pull Request!

This pull request is heavily inspired by the extraction of the MicrosoftGraph processor in #5854 and follows the same pattern.

The final goal is to add support for customized transformers just as the MicrosoftGraph processor. However, To make it easier to review I want to split it into two separate parts.
