Group Members CSV Export List doesn't match UI Members List

Summary

When exporting members using the Group Member Export feature, the CSV lists some users that are not showing in the UI.

The members have minimal access on parent group, are not direct members of the subgroup, but were added directly to underlying projects

Zendesk ticket: Internal Link

What is the current bug behavior?

The Export CSV lists members that are not showing in UI, but from underlying projects.

What is the expected correct behavior?

The Export CSV should show the members listed in UI only.

Proposal

• Align export and UI: Export should list the members that are visible in the Members tab (those are the members of the group that the user is currently looking at, but not members of any groups or projects underneath)
• Adjust documentation to clearly state what the export behaviour is focussing on
