You can only see this page if you are an owner or manager of at least one organisation.
On the "Members" page, you can filter and search for members and requests.
Click on the "Filter" button 
.
A pop-up menu opens.
In the menu, you can:
Search by name or e-mail by typing it in the search field.
Filter by status, group membership, role (only for Approved members), and import status (only for Approved members).
The chosen filters are automatically applied and are displayed
as chips. The filter returns results only for the current tab of the
"Members" page
("Approved members"
or "Requests").
To remove a single filter criterium, click the small X-icon
on the filter widget: 
To clear all filter criteria, click "Clear all" next
to the filter widgets. 
If you select filter criteria from two or more filter types (e.g. "Status" AND "Organisation role"), then only members to which all chosen filter criteria apply are shown.
If you select multiple filter criteria from one filter type, then all assets to which any of the filter criteria apply are shown in the list.
