How to add Users to a custom list who are added in SharePoint Groups?

I have a custom list 'AllGroups' with a column "Group URLs"  as hyperlink column. My SP site collection has several SP Groups. In the custom list, I add those groups URLs like "https://webapp/_layouts/15/people.aspx?MembershipGroupId=59" as items.

Now, I need to capture the user IDs of users who are added to any of the SP groups and add them to another custom list called "AllUsers". This is to make me perform a business logic using Allusers. Any idea on this?

Thanks in advance.
