Finding What Cmdlets a Role Has

Hybrid Environment - Exchange 2010 & Office 365

So I'm trying to find more information about our Role Assignment Policy and found the default obviously to be "Default Role Assignment Policy". I then found the following roles under it.

MyBaseOptions
MyRetentionPolicies
MyDistributionGroups-RE-Custom

I wanted to see what cmdlets MyDistributionGroups-RE-Custom has but can't seem to find the right combination of Powershell commands to achieve this.

Thanks in advance for your help.
