Function list_drafts 

pub async fn list_drafts(
    http: &Client,
    base_url: &str,
    access_token: &str,
    account: &str,
    limit: usize,
    skip: usize,
) -> Result<InboxPage, ClientError>

List a page of drafts from the Drafts folder. Drafts don’t have a real “received” time, so Graph sorts by lastModifiedDateTime desc here.
