Library for the graphical LCD 12864B V2.0 with ST7920 CHIP

I was able to operate it with i2c 20x4 lcd node

But only the first line works I cannot run the rest of the lines and write is mess up

Can a professional XOD member make custom node modification of this type of cheap screen that
helps build low-cost anti-covid19 systems?
this screen is our low cost option for emergency ventilator for covid19
useful links

Many thanks in advance
