@ Kim and David
This is likely to be fixed in the next update. It was rolled out without the switch in the Windows version, too. After the tremendous negative feedback they quickly released a switch in Word for Windows, but not he other apps. Word for Windows is the most used app. By quickly, I mean within days and ahead of schedule.
Do use the feedback mechanisms to keep the heat on for the Mac versions. Again, a fix has been promised.
This is a user-to-user support forum. -- You can give feedback TO MICROSOFT designers and decision makers on Microsoft Word or other Microsoft Products using their feedback mechanisms, (not here). (This is a link to directions.)
This is a relatively new issue and has been the subject of many posts. I agree that it was a big mistake on Microsoft's part. Please read the suggestions in other questions on this issue. If the thread is marked as answered, read the other posts as well. Some responses are about the Windows version. If they talk about File > Options, they do not apply to the Mac version. Here are some of these threads.
Again, if something has been marked as an answer, look at all the responses, not just that one. Pay special attention to responses from Bob Jones.

Based on feedback from some users in other language communities, it appears that you can currently turn off Copilot directly in Word for Windows, but other Microsoft 365 apps (such as PowerPoint, Excel, and Outlook) don't yet offer this option.
***
However**, Copilot Controll is not currently available for Mac apps.** The Microsoft development team expects to enable it for one or more apps in the next few weeks or so. I'm sharing this with you to let you know that Microsoft values user input and feedback, and that the Microsoft development team has taken note of user issues and is actively working on improvements.

In the meantime, I'd like to share with you that the Microsoft development team has noticed this issue and is gradually rolling out features to allow users to choose whether or not to use Copilot in Office. You can wait until the latest features are implemented before upgrading to use them, thank you for your understanding and patience.

The basic advice is to wait for Microsoft to fix it.
Otherwise, roll back to a previous version.
A third option is to change your subscription to "classic" Microsoft 365. That involves contacting Microsoft and asking to cancel your subscription and letting them talk you into staying with them but without the IA.
