Teams Graph API, Retrieving files from each Teams channel

Question

I am trying to retrieve all of the files associated with each channel within each Team. Per the Microsoft Graph REST API V1.0 documentation, it is GET /teams/{id}/channels/{id}/filesFolder.\

Please see https://docs.microsoft.com/en-us/graph/api/channel-get-filesfolder?view=graph-rest-1.0&tabs=http

However, filesFolder no longer appears as an available query. Is there still a way to achieve this?

Edit: Appears to be the same for Messages. https://docs.microsoft.com/en-us/graph/api/channel-list-messages?view=graph-rest-beta&tabs=csharp&viewFallbackFrom=graph-rest-1.0

Why are these queries no longer available?

Answer 1

You can query Groups with team-id to get the items from the group's drive directly.

You can use https://graph.microsoft.com/v1.0/groups/{team-id}/drive/root/children where /drive/root can get the Document library that the channel folders are part of and /children can display all items from the folder. Referto this doc for more details on how to get a DriveItem.
