admin/root impersonate activity should be locate in audit.log too.

Hi,
When admin does impersonating action, log show in nextcloud.log file. But after all activities by users name shown in audit log. When auditors examine audit log, they supposes that, those activities have bben done by user, but wrong. Those activites done by admin. Thats why I think that, impersonate activity should be in audit log too.
Thanks.
