Before enabling Call Explorer, the Salesforce Agentforce Specialist must ensure that the Einstein Conversation Insights permission set is assigned to users (Option C). Call Explorer is a feature within Einstein Conversation Insights (ECI) that analyzes meeting recordings to surface trends, keywords, and actionable insights.

Key Considerations:

Permission Set Requirement:

Users (including admins) need the Einstein Conversation Insights permission set to access and use Call Explorer. Without this, the feature remains inaccessible.

The permission set grants access to ECI tools, including call transcription, analysis, and dashboard visibility.

Why Other Options Are Incorrect:

A. Independence from Salesforce Knowledge: While Call Explorer does not rely on Salesforce Knowledge, this is irrelevant to the setup prerequisite. The critical dependency is the permission set, not Knowledge configuration.

B. Custom Actions: Call Explorer does not require custom actions to be built before configuration. It is a pre-built analytics tool that works once permissions and data sources (e.g., call recordings) are configured.

Salesforce Einstein Conversation Insights Guide: Explicitly states that the Einstein Conversation Insights permission set is required to access Call Explorer.

Trailhead Module: "Einstein Conversation Insights Basics" outlines permission prerequisites for enabling call analytics.

Salesforce Help Documentation: Confirms that Call Explorer functionality is governed by ECI permissions.
