List shared emails and meetings with a workspace contact (v2)

Emails and meetings with one workspace contact from every member account shared with the workspace at a content level, read live through each sharing member's own Google or Outlook account and redacted to that account's level: metadata gives subject or title, sender, participants (never Bcc) and dates; full adds the email snippet or event description. Optional kinds (comma-separated subset of emails,calendar; both by default) and limit (1–100, default 50). Newest first, capped at limit and not exhaustive: each account is read within a bounded window (calendar about two years back). partial: true means at least one shared account could not be read this time. Each item names the members whose shared accounts held it (member_user_ids) — not every teammate who took part — and the most permissive level among them (visibility). has_body marks a full-level email whose body the Dex app can open; bodies are not available over the public API. Accounts shared at dates only, or not shared, contribute nothing; a shared account's own address, provider links and raw payloads are never returned. Returns { data: { shared_activity: { items, partial } } }.
