How to change the label position when plotting venn diagram from eulerr package in R?

Question

I am trying to create a scaled venn diagram using the eulerr package in R.

My Code is below:

plot(euler(c( "LUTS"=98, "Symptoms of UTI"=46, "Positive urine culture"=39, 
              "Symptoms of UTI&LUTS"=33, "LUTS&Positive urine culture"=24, 
              "Symptoms of UTI&Positive urine culture"=22, "Symptoms of UTI&LUTS&Positive urine culture"=18),
           input = "union", shape = "ellipse"), key = TRUE, counts = TRUE, 
     quantities = list(type = c("counts", "percent"), font=3, round=2, cex=0.8), 
     fills =list(fill=c(viridis::plasma(n = 3))), alpha = 0.3, c("#1957FF", "#FF750C", "#FF220C"), alpha = 0.3, 
     edges=list(lty = 1), factor_names = TRUE, labels=list(font=2, cex=1), legend = FALSE)

The output:

How do I get the percent values to print below the count values? Something like this:

Unless I'm missing something in the docs, I don't see the option to do this. However, since plot.euler produces a grob tree, we can edit the output with a bit of grob-hacking:

library(eulerr)

v <- plot(euler(c( "LUTS"=98, "Symptoms of UTI"=46, "Positive urine culture"=39, 
              "Symptoms of UTI&LUTS"=33, "LUTS&Positive urine culture"=24, 
              "Symptoms of UTI&Positive urine culture"=22, 
              "Symptoms of UTI&LUTS&Positive urine culture"=18),
           input = "union", shape = "ellipse"), key = TRUE, counts = TRUE, 
     quantities = list(type = c("counts", "percent"), font=3, round=2, cex=0.8), 
     fills =list(fill=c(viridis::plasma(n = 3))), alpha = 0.3, 
     c("#1957FF", "#FF750C", "#FF220C"), alpha = 0.3, 
     edges=list(lty = 1), factor_names = TRUE, labels=list(font=2, cex=1), 
     legend = FALSE)

tags <- v$children[[1]]$children[[1]]$children$tags$children

tags <- do.call(grid::gList, lapply(tags, function(x) {
  x$children[[2]]$label <- sub(" \\(", "\n(", x$children[[2]]$label)
  x$children[[2]]$just <- NULL
  x$children[[2]]$hjust <- 0.5
  x$children[[2]]$vjust <- 1
  x}))

v$children[[1]]$children[[1]]$children$tags$children <- tags

v
