This fixes the error:
  unknown permission test at /usr/share/perl5/PVE/RPCEnvironment.pm line 536. 
(500)
which occured when trying to create or update a notification target.

The cause was a permission 'check' parameter for the API handlers which was 
nested
one level too deep by accident.

This regression was introduced in a previous commit which raised the
needed permissions for notification target management. It likely went
unnoticed because the permission check is skipped for root@pam, so
the error occurs only if using another user.

Reported in the community forum:
https://forum.proxmox.com/threads/158101

Fixes: a3fe9c54 ("api: notifications: require powerful privileges for target 
management")
