3535* **Sharing:** no channel in the pairing is shared outside its workspace. That rules out Slack Connect channels, including ones with a pending invitation, and channels shared across the workspaces of an Enterprise Grid.
3636* **You:** you are a member of every managing channel you add.
3737* **Managing channel:** its [**Channel member edits**](/docs/claude-tag/admins/attach-to-scope#restrict-who-can-set-channel-instructions) setting resolves to **Allow**. The list accepts a managing channel set to **Block**, but Claude refuses every read and change there.
38* **Managed channel:** the channel has its own channel scope on the **Slack** tab in admin settings. If it doesn't appear there, [add the channel](/docs/claude-tag/admins/attach-to-scope#attach-to-a-channel).
38* **Managed channel:** the channel has its own page on the **Channels** tab under **Claude's access** in admin settings. If it isn't listed there, [set the channel up](/docs/claude-tag/admins/attach-to-scope#attach-to-a-channel).

4040A managed channel can have up to five managing channels. A private managed channel has extra rules, listed under [Public and private channels](#public-and-private-channels).
