How to save a variable in non-volatile memory?

Hello,
I'm using a STM32F091VBTx microcontroller and for the application I'm implementing I need a variable to be constantly updated and it must be stored in a non-volatile memory in order to keep its value even if the microcontroller resets. I've found AN2594 about EEPROM emulation, but the functions described there are not available for the microcontroller I'm using. Should I use the functions provided in the stm32f0xx_hal_flash.c file? If yes, I would like to know if there is a demo software for this or if there is any other method to update values in a non-volatile memory.

Thanks.
