Deprecation warning for size argument in element_line()

[Thokas99]

When using the correlationfunnel (version: 0.2.0), I receive the following warning:

The size argument of element_line() is deprecated as of ggplot2 3.4.0.
ℹ Please use the linewidth argument instead.
ℹ The deprecated feature was likely used in the correlationfunnel package. Please report the issue at https://github.com/business-science/correlationfunnel/issues.
This warning is displayed once every 8 hours.

Steps to reproduce:

Load the correlationfunnel package.

Run

library(correlationfunnel)
correlationfunnel::plot_correlation_funnel()

Session info:

The warning suggests replacing size with linewidth in calls to element_line().
