Purview-Retention Policy for Private channels

I have retention policy for Standard & Shared channels together with 2 Years retention period to keep posts for 2 years and remove after that period. Don’t have any policy for Private channels posts/messages, so posts will be available indefinitely . With this https://www.microsoft.com/en-in/microsoft-365/roadmap?id=500380from Microsoft my private channels will also part of the same policy which is applied for standard & Shared channels . in this case how i can retain the posts from private channels indefinitely . Please suggest

  • Historically, the compliance copies of private channel messages were stored in a hidden folder within the user's mailbox, which is why the scope of the Private Channel retention policy was targeted at user mailboxes. Now, private channel messages are being migrated to a hidden folder in the team's group mailbox, so they will be stored alongside the compliance data for general and shared channels. This means that any Teams channel retention policies scoped to group mailboxes will apply to all data from general, private, and shared channels within Teams for groups covered by the policy. There is no way to specify a policy to include or exclude specific channel types because the scope is defined at the group mailbox level. See Learn about retention for Teams | Microsoft Learn
