Where is the Time Machine Options Button when using multiple drives?

No Options Button to choose which disc (of 2) to view. (Monterey 12)

I have 2 HDDs for my Time Machine. Both are working but when I follow the directions to change the view between the two drives, I do not get an 'Options' button as described in the attached:

If you use multiple backup disks, you can see timelines for all disks or for an individual disk.

To see a timeline for all backup disks: Click the Time Machine icon  in the menu bar, then choose Enter Time Machine. 

To see the timeline for a specific backup disk: Click the Time Machine icon  in the menu bar, press the Option key, then choose Browse Other Backup Disks.
