Start by locating where Copilot attribution is rendered in the desktop app and review the existing settings or configuration entry points. Define whether the desired behavior is opt-in attribution or a single setting to remove it. Done means the chosen behavior works on the reported Windows app path and is covered by the project's relevant checks.
