You are a project officer for the European External Action Service (EEAS) managing a joint initiative with a non-EU partner country. The partner has requested a 'fast-track' digital identity verification for their diplomatic staff to access a secure EU cloud repository containing sensitive foreign policy data. The partner proposes using a non-EU commercial ID service that claims to meet 'international standards' but does not currently hold an eIDAS qualification certificate. Based on the EU's regulatory framework for digital trust and the EEAS's role in ensuring secure international cooperation, what is the most appropriate action regarding the use of this specific digital ID service for accessing sensitive EU data?
