When you send the file, you'll be warned if the room or someone in a direct message doesn't have access. If you have Edit access to the file, you'll see an option to grant access. If you grant access to a Space, it also applies to people who join the Space later. If people leave the Space, they lose access to the file unless they’re given access individually or through another group.
