For the report purpose, we need to get the exported images of Status/Hardware/DBStast.
With personal authentication, I can get these images via URL:
https://cloud.mongodb.com/export/v2/charts/{status/hardware/dbstast}/{clusterID}/{hostID}/{format}/{title}?since={since}&until={until}&hostDbStatsName={DBName}

Ex: https://cloud.mongodb.com/export/v2/charts/hardware/602329750202ff2349345de6/807910899a141fbdc82fbea63528bf6d/png/null?since=1635754200000&until=1635840600000&hostDbStatsName=14313

However, I cannot get it programmatically with API Key authentication.

Let's allow the image export using Atlas Admin API.
Thanks!
