It can process specific group IDs or search all groups for PIM eligibility. Optionally, it retrieves assignment settings for each group and translates object IDs to display names for easier interpretation. .PARAMETER groupId One or more Azure AD group IDs to process. If not specified, all possible PIM-enabled groups will be searched. .PARAMETER skipAssignmentSettings If specified, the function will not retrieve assignment settings for the roles. This can speed up the function if you don't need the detailed settings. .EXAMPLE Get-PIMGroupEligibleAssignment Returns all Azure AD groups with PIM eligible assignments and their assignment settings. .EXAMPLE Get-PIMGroupEligibleAssignment -groupId "12345678-aaaa-bbbb-cccc-1234567890ab" -skipAssignmentSettings Returns PIM eligible assignments for the specified group, skipping assignment settings for faster results. .NOTES Author: @AndrewZtrhgf #> [CmdletBinding()] param ( [string[]] $groupId, [switch] $skipAssignmentSettings ) if (!(Get-Command Get-MgContext -ErrorAction silentlycontinue) -or !(Get-MgContext)) { throw "$($MyInvocation.MyCommand): Authentication needed.
