RoleEligibilitySchedule.Read.Directory missing when RoleEligibilitySchedule.ReadWrite.Directory is set

[tbalthazar]

Context

I'm using Maester with Azure DevOps, as documented here.
The Service Principal has RoleEligibilitySchedule.ReadWrite.Directory but doesn't explicitly have RoleEligibilitySchedule.Read.Directory.
My understanding is that the ReadWrite permission is a superset of the Read permission.

What happens

The pipeline execution fails with this error:

Exception: /home/vsts/.local/share/powershell/Modules/Maester/1.0.0/internal/Test-MtContext.ps1:44

     | These Graph permissions are missing in the current connection =>

What I think should happen

It shouldn't fail since RoleEligibilitySchedule.Read.Directory is contained in RoleEligibilitySchedule.ReadWrite.Directory.
