The DWP will not consider a covert recording during an MR, a Tribunal Judge can admit is as evidence but it would be rare for them to do this, appeal hearings are around 45 minutes and the panel will be far more interested in investigating how and why the claimant meets the criteria for an award than what was and was not said during the assessment.
You could submit a transcript of the recording but again don't expect the panel to focus on it.
