Order Bars in interactive graph - r

Question

I am creating an interactive graph using ggplot2 and plotly in R, the code is below.
I want to reorder the barchart column values so that they are sorted in descending order,
currently they are sorted alphabetically.
Edit: I might not have made what I wanted clear. Currently, the midfielder with the most points is Salah, but the top row in my midfielder column is currently Alli. I would like to sort the column so that the values are in descending order of points rather than alphabetical.
Would someone please inform me how I can do this?
I have saved the finished graph & csv file at the below locations:
