🤖 Member apps can now be shared with a group. Building your own app in App
Studio and want the whole chat to use it, not just you? Declare it
group-capable and anyone in a group can add it (⋮ → Add apps) — everyone gets
one shared instance, same as adding a person, visible to the chat and just as
easy to remove. As always, it's a member-built tool, not admin-reviewed code,
so it's shown as such wherever it's added.
