Switching mouse buttons

Hi,

Long time user, great product. Recently we upgraded to OSX Ventura, and infuriatingly it does not show mouse options in System Preferences for wired mice - only bluetooth mice.

As such, my wife (who uses the mouse left handed) can not switch mouse buttons. I figured BetterTouchTool would have my back here, and sure enough I can switch the mouse buttons using it.

However, she can no longer mouse drag once the buttons are switched. I tried adding a second shortcut for left click with ctrl modifier to start/stop mouse dragging, and that seemed to revert the mouse buttons after the first use. I then tried to add a keyboard shortcut to start/stop mouse dragging and that didn't work either.

Please could you provide some guidance?

Many thanks
