When attempting to use the GARCH-MIDAS model, I encountered an error message stating 'unused argument (k = 2)

Read data from an Excel file

data1 <- read_excel("C:/Users/illuion_wqy/Desktop/bit.xlsx")

fit_mfgarch(data=data1, y="return", x="EPU", low.freq="year_month",k=2)

#Error in fit_mfgarch(data = data1, y = "return", x = "EPU", low.freq = "year_month", :
