Currently, when we fetch users from an organisation we fetch all users plus all open invitations. However, we then need to remove those open invitations as the users don't have IDs and thus cannot and should not be added to collections.

With the changes here: https://camunda.slack.com/archives/CKZK2E7RP/p1670422606523819?thread_ts=1666359028.737109&cid=CKZK2E7RP

It is now possible to filter for just accepted users and exclude invited users from the response. We should make this small change to prevent fetching more users than necessary in Cloud SaaS environments

Testing Notes:

• Regression test that users are available in Optimize collections
• Test this in an organisation that has invited members that have not yet accepted their invitation. Those invited users should not be available as collection users in Optimize
