Add a legend for quantile plot(grqreg)

[John Statanew]

Based on below command I run a quantile regression but I can not add a legend. Could you please advise me how can add a legend for quantile plot?

qreg yield_1 ndre_20 dem_16, quantile(.5)

grqreg, ci ols olsci

The Below code did not work:

 grqreg, ci ols olsci || legend(on)
error option legend() not allowed

grqreg, ci ols olsci ||, legend(on)
error option legend() not allowed

grqreg, ci ols olsci, legend(on)
error option legend() not allowed
