a named list with at most two elements. It will
always contain a list, named records
,
of objects of type insight_summary_response
.
If the call to get_insights()
was made with a non-null
limit
parameter, and if further pages remain for
retrieval, then
the list will also contain a single-element character vector,
named next_page_token
,
with the token to use in a subsequent call to get the next page.
