Seeking Suggestions: Tracking User Removal from Group and Identifying Group Update Details

I have a requirement where we need to track who removed a user from a group. Additionally, when a user updates the group and their name appears as the last modifier, it's challenging to identify the specific user who removed another user, especially when multiple users have recently updated the group. Can you provide suggestions on how we can address this?

Thanks & Regards,

Nisha Vincent.
