When an app asked for an authentication via Wikipedia for "High-volume editing" the first response is shock. Why would this supposedly read-only tool be needing this?
I assume the grant is for generic "bot". In this case for "noratelimit" and "apihighlimits". But please don't call it editing because it is incorrect (rate limit applies to edits, but also other non-edit actions; and apihighlimits only applies to queries, not edits), and simply wrong (this grant does not provide the "edit" right at all).
