Thank you for you post!
I understand that you are looking for a way to add a column to the Microsoft Azure Groups
The Microsoft Entra screen is a default view that cannot be customized and there is no built-in feature to display the number of members in each group directly on the main screen. However, you can achieve this by using PowerShell scripts to generate a report that lists all your Azure AD groups along with their member counts.

Hope this helps. Do let us know if you any further queries.
