How will it work? I open an Excel spreadsheet and also the AI Copilot. Then whenever I want to do something with Excel like "Show me which cells have formulas" CoPilot will interact with Excel and issue some command I cannot remember to do that for me? Menus are good but often hard to navigate and find. So the CoPilot can give me a whole new (prompt-based) user-interface to any MS-application? Is that how it works?
