GroupManagementInterface

What it does

This interface defines the contract for managing customer groups in Magento 2.

Developers use this to retrieve different types of customer groups (default, logged-in, not logged-in, all customers) and to check if a group can be deleted.

It's commonly used when implementing custom pricing, promotions, or access control based on customer group membership.
