I am trying to change the size of an arrow.
In the function arrow I can set headlength and headwidth but this does not change the arrow size in the plot.
How can I change the arrow size in a plot?
Julia: v1.10.4
Plots: v1.40.5

using Plots

plot([0,1], [0,1], label="Bool", arrow=true)
plot!([0,1], [0,.8], label="Closed", arrow=:closed)
plot!([0,1], [0,.6], label="Closed lw5", lw=5, arrow=:closed)
plot!([0,1], [0,.4], label="Closed size0.9", arrow=(:closed, 0.9))
plot!([0,1], [0,.2], label="arrow", arrow=arrow(:closed, 0.9))

arrow()
#Plots.Arrow(:simple, :head, 0.3, 0.3)

arrow(:closed, 0.9)
#Plots.Arrow(:closed, :head, 0.9, 0.9)
