Show the x and y values on hoover on line graph

Hi Experts

I am new to R Script and coding, just inherited some R Code that i which plots perfectly fine and gives the correct results. I want to have the ability to show the x and y values when a user hoovers the mouse cursor over the line.

I have found a link to a articles that describe how to carry out the necessary step but having no luck at all..

my r code.

library(dplyr)
library(ggplot2)
library(survival)
library(survminer)
library(grid)
library(gridExtra)
library(plotly)
pc <- dataset
fstat <- pc %>% mutate(fstatus = case_when(OUTCOMETYPE=="Revised" ~ 1,TRUE ~ 0))
pmpa <- fstat %>% select(PRIMARYPROCEDUREID,PRIMARYTOOUTCOMEYEARS,fstatus,OUTCOMETYPE)
if(nrow(pmpa) < 4){
d <- pmpa %>% select(PRIMARYPROCEDUREID,PRIMARYTOOUTCOMEYEARS,OUTCOMETYPE) %>% mutate(INSUFFICIENTDATA = "Summary Results")
h = head(d[,2:4])
grid.table(h)
}else{
fit <- survfit(Surv(PRIMARYTOOUTCOMEYEARS,fstatus)~1,data = pmpa) 
ggsurv <- ggsurvplot(fit,
           ylab="Patient Analysis",
           xlab="Time (Years)",
           break.time.by = 1,
           xlim = c(0,max(fit$time)),
           surv.scale = "percent",
           legend.title = "Kaplan-Meier",
           legend.labs = "",
           risk.table = TRUE,
           fontsize = 3,
           font.tickslab = c(10, "plain"),
           risk.table.y.text = FALSE,
           fun = "event"
           )
ggsurv$plot <- ggsurv$plot + theme(plot.title = element_text(hjust = 0.5, size=18), panel.grid.major = element_line(colour ="grey90"))
ggsurv$table <- ggsurv$table + theme(plot.title = element_text(hjust = 0.5, size = 10))
