error: passing 'const SerialMenu' as 'this' argument discards qualifiers [-fpermissive]

Hi, I'm trying to use this library on a Arduino Zero but getting the following error when trying demo2 :
Arduino IDE ver 1.8.12

seems to affect the load and getNumber methods

demo2.ino: In lambda function:
demo2:39:74: error: passing 'const SerialMenu' as 'this' argument discards qualifiers [-fpermissive]
{"> - Sub-menu", false, '>', { menu.load(subMenu, subMenuSize); menu.show();} }

note: in call to 'void SerialMenu::load(const SerialMenuEntry*, uint8_t)'
inline void load(const SerialMenuEntry* array, uint8_t arraySize)
^~~~

I also had to add "#include <Arduino.h>" to the hpp file or it could not find "Serial"
