Amy is an Org Owner on an Enterprise Grid plan.
A workspace Admin informs Amy that a confidential file has been uploaded to a public channel by mistake.
Amy needs to remove the file and determine who has downloaded it.
What should Amy do to accomplish this goal?

You are a Workspace Owner and the product manager for a snowboard manufacturing company based in Vancouver, Canada.
As product manager for the company's RebelX line, you are responsible for all aspects of production, including managing your supplier relationships. You have a connected channel called #supplier-bindings with one of your suppliers based in Osaka, Japan, and you use this channel to plan shipments of bindings and manage all interactions with this supplier.
Unfortunately, one of the supplier's deliveries has not arrived, and if you don't receive it by next week, your inventory and sales will be negatively affected.
Because of the timezone difference, you need to notify all channel members about the delay so they are aware as soon as possible or tomorrow morning at the start of the business day.
What should you do?
