Customising Composition Mode

In the Scrivener Tutorial, the following paragraph occurs in the “Composition Mode” document:

You can customise the look of composition mode in the “Appearance” tab of the Options. By default, the regular text colour is overridden to appear as white on a dark grey-blue background, but you can change this to use black-on-white, green-on-black or anything you want.

I cannot find an Options menu/icon or an “Appearance” tab! Any help would be greatly appreciated! Many thanks.

On windows: File > Options > Appearance > Composition Mode

On Mac: Scrivener > Preferences > Appearance > Composition Mode

Many thanks, @AntoniDol
