Nucleo-L031K6 internal EEPROM

Hi in my project, I need to store data to internal eeprom of my board Nucleo-L031K6. I have tried this code:

HAL_StatusTypeDef writeEEPROMByte(uint32_t address, uint8_t data)
 {
   HAL_StatusTypeDef  status;
    address = address + 0x08080000;
    HAL_FLASHEx_DATAEEPROM_Unlock();  //Unprotect the EEPROM to allow writing
    status = HAL_FLASHEx_DATAEEPROM_Program(TYPEPROGRAMDATA_BYTE, address, data);
    HAL_FLASHEx_DATAEEPROM_Lock();  // Reprotect the EEPROM
    return status;
}

uint8_t readEEPROMByte(uint32_t address) {
    uint8_t tmp = 0;
    address = address + 0x08080000;
    tmp = *(__IO uint32_t*)address;
    
    return tmp;
}

but it's work fine for me only for address 0. Can someone suggest me whats I can do? .....or alternative code? Thanks
