NCMAddNode - WebViewer permission required

Hi all, 

i am trying to add a node to NCM via Python but i am getting permission denied, this node has already been added to Orion.Nodes with Create. i have checked with our SW admin and he said that i have admin rights, but i am still getting this error.

result = swis.invoke('Cirrus.Nodes', 'AddNodeToNCM', nodeid)

requests.exceptions.HTTPError: 403 Client Error: Access denied. 
    WebViewer permission required. 
    for url: https://1.1.1.1:17778/SolarWinds/InformationService/v3/Json/Invoke/Cirrus.Nodes/AddNodeToNCM

do you know what kind of permission i need to get this done?
