Add the option of importing groups via a csv file
There's no option in the GUI to import groups with a csv file. This is especially troublesome for people who have to transfer groups from older exchange servers into Microsoft 365. Your current system requires using Microsoft Powershell which is awful software. Powershell syntax is unique to Microsoft and is not based solely on any other scripting language. Having to learn it is a huge waste of time for anyone who isn't a Microsoft employee.
If you insist on making people use the command line to upload groups then at least change it to MySQL syntax so you aren't forcing your users to spend hours on the phone with customer support, or waste hours learning the details of a proprietary scripting language.
