Read the activity log
To read a document’s log, callGET /documents/{id}/activity. It needs the READ_DOCUMENT_AUDIT_LOG workspace permission. The response is a page of events, newest first:
cursor set to nextCursor until hasMore is false. For more information, see Pagination.
The response leaves out IP addresses, user agents, and request metadata. Treat
type as an open list: sajn can add new types without a new API version.
