Midaxo released a new User Role on March 18, 2023.
Associates are able to Assign Task Responsible, and, when doing so, are able to see a complete list of ALL Users in your workspace.
They are the same as Project Members in every other way. So, they still need to be added to Groups and Projects, and you can still control their visibility on the Task level.
Please see the article here regarding Task Permissions for Associates.
