[Sentinel] - Discussion to remove listed token option

[ngmachado]

The current usage of Listen Token in our system seems to be a legacy artefact from an time when we did not have the necessary features for detailed token filtering.

This feature introduces additional complexity to our codebase, which can potentially lead to maintenance challenges and impact readability.

At the moment, all tokens can be listed simply by making a pull request, making the Listen Token feature somewhat redundant. We should consider whether the Listen Token feature is still relevant in our current context, or whether alternative mechanisms might be more suitable for our needs.
