Native Integration between Fusion Service and Field Service

Hi Team,
This is a continuation of my previous question regarding Fusion Service to FFS native integration:
https://community.oracle.com/customerconnect/discussion/comment/1583976#Comment_1583976

We have successfully established the Fusion Service to Fusion Field Service (FFS) connection, and Work Order → Activity creation is working as expected using the native integration (without OIC/IDCS).

We would like to understand the behavior of standard plugins in this setup:

• Asset Details Plugin
• Debrief Plugin
• Parts / Parts Ordering Plugin

Question:
In a native Fusion–FFS integration (without OIC/IDCS),

• Will these standard plugins work out-of-the-box?
• Or do they still require additional setup such as IDCS authentication or OIC-based integration?
