Do we need to provide a back button on the DH (Data Holder) dashboard, for procedures like consent amendment?
Both the authorisation to disclose, and amending authorisation flows, use the prescribed CDR authentication model.
There is no requirement for a DH dashboard back button. A back button is a common and expected feature, however.
If you would like us to update the CX Standards to clarify this point we welcome you to raise a change request.
