Publishing WebTool but unable to add folder server

[Anonymous User]

I am using ArcGIS PRO and have AGOL license with publisher rights. I have a tool which i want to publish as a web tool. When i click on 'share as web tool', the tool does not allow me to add a server folder. I searched on the topic and found that I might need to change setting for "allowGPAandExtensionPublishingtoPublishers" to allow. Where can the admin find this setting and change it?
