How to set a label for a cluster in a dendrogram in R?

I want to insert a label in a box and in each cluster as shown in here:

But, What I obtained is:

Where the name of the cluster is in the specie label, not into the corresponding cluster as shown in the first figure.

My data is:

Specie;Cluster;A;B

My code is (Adapted):

setwd("C:/Users/david/OneDrive/Documents/R_Carpeta/2022_mid/2022_end")
iris<-read.csv(file="Dendrograma_Ds_2022_Nor-Grupos.csv", header=TRUE, sep=";")
Dg <- iris[,-1:-2]
row.names(Dg) <- iris[,1]
rest.dist <-dist(Dg,method="minkowski")
hc1_5 <- hclust(rest.dist, method = "average")
dend1_5 <- as.dendrogram(hc1_5)
#Color
iris_species <- rev(levels(iris[,2]))
dend1_5_c <- color_branches(dend1_5,k=5, groupLabels=iris_species)
is.character(labels(dend1_5_c)) # labels are no longer "integer"
labels_colors(dend1_5_c) <-
  rainbow_hcl(3)[sort_levels_values(
    as.numeric(iris[,2])[order.dendrogram(dend1_5_c)]
  )]
#Group labels
labels(dend1_5_c) <- paste(as.character(iris[,2])[order.dendrogram(dend1_5_c)],
                           "(",labels(dend1_5_c),")", 
                           sep = "")
dend1_5_c_L <- hang.dendrogram(dend1_5_c,hang_height=0.1)
dend1_5_c_L <- assign_values_to_leaves_nodePar(dend1_5_c_L, 0.5, "lab.cex")
par(mar = c(3,3,3,7))
plot(dend1_5_c_L, horiz =  FALSE,  nodePar = list(cex = .007))

In order to obtain a plot with branch labels, you need to provide a character vector as the groupLabels argument of color_branches of the same length of the number of clusters (in this case k = 5).

library(dendextend)
library(colorspace)

## import the dataset to `tab'

## set rownames
rownames(tab) <- with(tab, sprintf("%d (%d)", Cluster, Specie))

hc <-
    tab[,-c(1:2)] %>%
    dist(method = "minkowski") %>%
    hclust(method = "average") %>%
    as.dendrogram() %>%
    color_branches(k =5, groupLabels = LETTERS[1:5]) %>%
    assign_values_to_leaves_nodePar(nodePar = "lab.cex", value = 0.5) %>%
    hang.dendrogram(0.1)

plot(hc)
