How to onboard customer with multiple eligible authorisations

Question

How do I onboard a customer subscription but with multiple eligible Authorisations. The sample file listed here only shows you how to add one. Microsoft documentation does now show you how to onboard a customer with more than one eligible authorization. I've tried to add 2 PIM roles, and while the onboarding deployment succeeds, it only registers the one of the eligible authorizations. Sample file below:
