Try any one approach as per requirement
1. Disable Conference Calling via System Property
The most straightforward option — set this property to false:
glide.notify.conference.enabled → false
This disables the conference call initiation globally, which removes the "+" / "Initiate collaboration" button from the Calls tab. If you don't see this property, create it as a true|false type in sys_properties.
2. Deactivate or Don't Configure the Notify Plugin
If your org isn't using Twilio for any telephony at all, deactivating the Notify plugin (com.snc.notify) or simply removing the Twilio driver configuration will cause the Calls tab to either disappear or become non-functional. This is only appropriate if you're not using Notify anywhere else.
3. UI Builder Component Configuration
Since SOW is a Next Experience workspace, open it in UI Builder and locate the Collaborate panel component. Check if there's a configurable property on the component to hide the Calls tab or the conference action. The component may expose a showConferenceCalls or similar boolean config prop depending on your release version.
4. Role-Based Restriction
The conference call action typically requires the notify_user or snc_internal role. If you remove that role from your agent groups, they won't see the initiate option even though the UI element may still render.
