How to Bulk rename Security groups on AAD

Hi Team,

I'm trying to rename over 100 Azure security groups using PowerShell but I just can't get the script to work without errors. I want to add "NG" to the output of the GetAzADGroup command

# Get the group that we want to modify.
$Group = Get-AzADGroup -DisplayNameStartsWith 'test'

#Next line is to Import Csv with the new group name eg "NG-Test1, NG-Test2" etc #

Import-Csv -Path C:\Users\Prince\Downloads\exportGroup_2022-6-15.csv | ForEach{Set-AzureADGroup -ObjectID $.objectid -Displayname $.displayname}

I run into the following error "Set-AzureADGroup : Error occurred while executing SetGroup"

I'll appreciate any help or pointers to resolve this. Thanks in advance
