How to modify text in tbl_summary?

Question

I'd like to modify, in tbl_summary "Median (IQR)" by "median [Q1 : Q3]", and "Range" by "Min -Max" ?

I'd like that in the far left colomn, we'd read "median [Q1 : Q3]" instead of "Median (IQR)"

trial %>% select(trt, age) %>% 
tbl_summary(by = trt,
 type = list(all_continuous()  ~ "continuous2",
  all_categorical() ~ "categorical"),
    statistic = list(all_continuous()~ c("{N_nonmiss}",
                                        "{min} - {max}", 
                                        "{mean} ({sd})",
                                        "{median} [{p25} - {p75}]")))

You can use the add_stat_label() function from the same package.

library(gtsummary)
trial |> 
  select(trt, age) |> 
  tbl_summary(by = trt,
              type = list(all_continuous()  ~ "continuous2",
                          all_categorical() ~ "categorical"),
              statistic = list(all_continuous() ~ c("{N_nonmiss}",
                                                    "{min} - {max}",
                                                    "{mean} ({sd})",
                                                    "{median} [{p25} - {p75}]"))) |> 
  add_stat_label(label = list(all_continuous() ~ c("N",
                                                   "Min - Max",
                                                   "Mean (SD)",
                                                   "Median [Q1 : Q3]")))
