Thanks for the PR @shinde-rahul - please can you also raise it on the WIP new docs if you have a moment - I think this is the relevant page: https://github.com/mautic/developer-documentation-new/blob/main/docs/plugins/config.rst which can be previewed at https://mautic-developer.readthedocs.io/en/latest/plugins/config.html.

Important note: If this only applies to 5.x please make the PR on the 5.x branch of the docs, previewed here: https://mautic-developer.readthedocs.io/en/5.x/plugins/config.html.

Thanks!
