Usage

// Remote function fetches all groups
const groupsQuery = getGroups();

// Client-side filtering
let filteredGroups = $derived.by(() => {
  if (!searchQuery.trim()) return groupsQuery.current.items;
  return groupsQuery.current.items.filter(g => 
    g.name.toLowerCase().includes(searchQuery.toLowerCase())
  );
});

Updated GroupService to use /groups-management/ endpoint in commit cab1629. Both listGroups() and getGroup() methods now call the correct endpoints.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
