 The `anonymisedRtdProvider` must be integrated into the publisher's website along with the [Anonymised Marketing Tag](https://support.anonymised.io/integrate/marketing-tag?t=LPukVCXzSIcRoal5jggyeg). One way to install the Marketing Tag is through `anonymisedRtdProvider` by specifying the required [parameters](https://support.anonymised.io/integrate/optional-anonymised-tag-parameters?t=LPukVCXzSIcRoal5jggyeg) in the `tagConfig` object.
