Is it possible (how) to have different line widths for different groups in ggsurvplot figure in R?

Question

I want to change the line width for different groups plotted in the same figure using ggsurvplot. Something like this:

    plot = ggsurvplot(curve_fitted_open,
                  fun = 'event',
                  conf.int = FALSE,
                  xlim = c(0, 365),
                  ylim = c(0, 1),
                  linetype = c('solid', 'dashed'),
                  size=c(1, 0.5))

I.e. I would like to set the line width (see the last line in the example) in a similar ways as the line type but this does not seems to work. Is there another way to do this?
