Counts of giant RC and RGB stars with IR excesses as function of Li abundance in dex as obtained in this work. This figure must be compared with a similar figure of YA21 based on asteroseismology data (Figure 1 in YA21). Using short horizontal lines, we present the regions coincident with the presence of minimums and maximums of the figure of YA21. In our work, we eliminated all bright RC giants stars with log-g values under 2.2 for which no astroseismology calibration exists following YA21.
