File on the ribbon not there

Hi all.

My goal is to disable the zoom on roll with the Apple Intelimouse. I am using Excel v. 16.44

to do this I believe the following process is required:

Open Microsoft Excel on your computer.
Click on the File button located at the top left corner of the window.
Click on Excel Options.
Go to the Advanced tab to view the advanced settings.
On the right-hand pane, uncheck the box associated with the option Zoom on roll with Intellimouse.
Click on OK to save the changes and restart your computer.

All sounds fine, but....

*** There is no File button in the top left of the ribbon - just begins with the Home button.

How do I get it back so I can get to options.

Thanks in advance.
