FilesFolder is not created automatically for newly created private channels

Question

When I create a new private channel and then try to get the FilesFolder, it is always null. Even a few hours after creation, the FilesFolder is still null. It will only be created, when a user manually clicks on the Files tab in Microsoft Teams.

Expected behavior

One of the following behavior is expected:

• The FilesFolder should automatically created after the private channels creation
• There should be an operation to create the FilesFolder of a private channel by Microsoft Graph Api

Actual behavior

FilesFolder always stays null. There is no possibility to get access to the FilesFolder of a private channel without manual interaction. E.g. when you want to create a new private channel and then create a folder structure like that:

Steps to reproduce the behavior

1. Create new Channel

Channel channel = await graphServiceClient.Teams[teamId].Channels.PostAsync(new Channel
  {
  DisplayName = "My Private Channel",
  MembershipType = ChannelMembershipType.Private
  });

2. Get FilesFolder of the newly created channel

DriveItem filesFolder = await graphServiceClient.Teams[teamId].Channels[channel.Id].FilesFolder.GetAsync();

3. Further operations with the FilesFolder (not possible due to "filesFolder" is always null)

string driveId = filesFolder.ParentReference.DriveId; 
DriveItem createdFolder = await graphServiceClient.Drives[driveId].Items[filesFolder.Id].Children.PostAsync(new DriveItem {   Name = "My Folder",   Folder = new Microsoft.Graph.Folder() });

I moved this issue from https://github.com/microsoftgraph/msgraph-sdk-serviceissues/issues/30 because they are closing that repository.
