How to show labels in geom_text that is proportional to geom_bar group variable

$

I have been trying to output in ggplot a graph that shows labels in percentage value and in proportion to the grouping factor defined in geom_bar. Instead of % values proportionate to the overall population, I would like to output a label value that is proportionate to each sub-group (in this case Place A and Place B) but I have not managed to. See below the reproducible example

Reproducible dataframe

Random<-data.frame(replicate(3,sample(0:3,3024,rep=TRUE)))
Random$Trxn_type <- sample(c("Debit", "Credit"),
                       size = nrow(Random), 
                       prob = c(0.76, 0.24), replace = TRUE)
Random$YN <- sample(c("Yes", "No"),
                       size = nrow(Random), 
                       prob = c(0.76, 0.24), replace = TRUE)
Random$Place <- sample(c("PlaceA", "PlaceB"),
                       size = nrow(Random), 
                       prob = c(0.76, 0.24), replace = TRUE)

Random<-Random[, 4:6]

Then applied the following code

Share<-ggplot(Random, aes(x = YN, fill=Place)) +
scale_fill_brewer(palette="Greens")+
geom_bar(aes(y = ..prop.., group = Place),position = position_dodge()) + 
facet_wrap(~ Random$Trxn_type, scales = "free_x", ncol=2)+ 
theme(strip.text.x = element_text(size = 15, colour = "black"))+
theme(panel.background = element_rect(fill = "white"),legend.position = "bottom")+
scale_y_continuous(labels = percent)+
ylab("Frequency") + 
coord_flip()+ 
xlab("Answers") + 
theme(plot.title = element_text(size = 16, face = "bold"),
      axis.text=element_text(size=12),
      axis.title=element_text(size=12))+
geom_text(aes(y=..prop..,label=scales::percent((..count..)/tapply(..count..,..PANEL..,sum)[..PANEL..])),
          stat="count", vjust=-.5, position=position_dodge(.9)) 
Share

And got the following output

enter image description here

Instead of this percentage distribution I would like to see the % value of replies considering Place A and Place B as two separate populations, or put it more simply I would like the labels to show the % value corresponding to the size of the histogram bars. Thanks!
