Fixing https://feedback.getalby.com/-alby-hub-request-a-feature/posts/message-when-deleting-isolated-connection

When deleting an isolated connection I think it would be good if there was a message advising what happens to the sats that are associated with that connection.

I think it could be easy to get the fear that sats may be lost. Perhaps a line advising people that no funds will be removed and will still be available from the main wallet could be added to the message in the included screenshot.
