Increasing menu item thickness in custom app?

I have a menu in my app:

var mainMenuItems = {
  "":{"title":" "},
  "Lying Down": () => showConfirmationMenu("ly"),
  "Sitting": () => showConfirmationMenu("si"),
  "Standing": () => showConfirmationMenu("st"),
  "Delete last": () => deleteLastLog()
};

var mainMenu = E.showMenu(mainMenuItems);

The buttons are so narrow compared to my fingertip and it is hard to even tell if I'm pressing the right buttons even if I'm very carefully and slowly pressing them.

Is there any way to widen buttons? Whether making the font taller or just padding above and below the text on each button?

I saw something about fontHeight in the graphical_menu library, but that doesn't seem to do anything here.
