I am adding a label on top of a bar in Pine Script. However, the label’s position changes with each new candle because the bar index changes. How can I add a label fixed to a specific index?

xlabel= label.new(bar_index[5],high, text = "TEST", color=color.lime, yloc = yloc.abovebar)
label.delete(xlabel[1])

I tried this, but it didn’t work..

xindex= chart.point.from_index(bar_index, high)
