### Conflicting statements regarding content exclusion support in IDEs

There appears to be a contradiction in the GitHub documentation for [Configuring content exclusion for your repository/organization/enterprise](https://docs.github.com/en/copilot/how-tos/configure-content-exclusion/exclude-content-from-copilot).

1. Early in the page, it states:

> "GitHub Copilot CLI, Copilot coding agent, and Agent mode in Copilot Chat in IDEs, do not support content exclusion."

This indicates that content exclusions **do not work** in IDEs when using Copilot through these modes.

2. Later, the documentation provides instructions for testing content exclusions in IDEs (VS Code, JetBrains, Visual Studio, Vim/Neovim), implying that exclusions **do work** in IDEs, which contradicts the earlier statement.

**Suggestion:**
- Clarify which parts of Copilot respect content exclusions.
