R: ggplot2 images as y-axis labels - r

Question

I am trying to add images to a y-axis label. At the moment I am only able to add them inside the graph. You can find the code for the added images at the bottom of the code chunk. I want the flags to be displayed after or under or on top of the country name.
Does anybody know how to do it or where I can find a tutorial?
p <- ggplot(data, aes(x = country, y = thisyear)) +
geom_segment(aes(
x = reorder(country, thisyear) ,
xend = country,
y = lastyear,
yend = thisyear
),
color = "#3b3b3b") +
geom_point(size = 3, color = "#f7931b") +
geom_point(aes(x = country, y = lastyear), color = "#BCBCBC", size = 4) +
geom_point(aes(x = country, y = thisyear), color = "#f7931b", size = 4) +
annotate(
"text",
label = "this year",
x = nrow(data) - 0.7,
y = data[2, 3] + 3,
size = 4,
color = "#f7931b",
fontface = "bold"
) +
geom_curve(
aes(
x = nrow(data) - 0.85,
y = data[2, 3] + 3,
xend = nrow(data) - 1,
yend = data[2, 3] + 0.5
),
colour = "#f7931b",
size = 1,
curvature = -0.2,
arrow = arrow(length = unit(0.015, "npc"))
) +
annotate(
"text",
label = "last year",
x = nrow(data) - 1.5,
y = data[2, 2] + 3.2,
size = 4,
color = "#A8A8A8",
fontface = "bold"
) +
geom_curve(
aes(
x = nrow(data) - 1.35,
y = data[2, 2] + 3.2,
xend = nrow(data) - 1.05,
yend = data[2, 2] + 0.5
),
colour = "#A8A8A8",
size = 1,
curvature = -0.15,
arrow = arrow(length = unit(0.015, "npc"))
) +
scale_y_continuous(expand = expansion(mult = c(0, .05))) +
coord_flip() +

theme(
panel.grid.minor.y = element_blank(),
panel.grid.major.y = element_blank(),
legend.position = "none"

subtitle = paste0(as.character(format(maxdate, "%B %Y")), " Monthly Average"),
x = "",
y = '%',

theme(
legend.title = element_blank(),
plot.title = element_text(color = "#f7931b"),
plot.subtitle = element_text(color = "#3b3b3b"),
plot.caption = element_text(color = "#646464", face = 'bold'),
panel.border = element_rect(
colour = "grey",
fill = NA,
size = 1
)
)
p <-
p + geom_image(data = data, aes(x = id, y = 70, image = emoji), size = 0.04)

SOLUTION
As suggested I have tried to add the images with the [ggtext][2] tutorial. First I had to make the label vector with the HTML code:
labels <- c()
for (i in 1:length(data$emoji)){
img.name <- data$country[i]
labels <- c(labels, paste0("<img src='", data$emoji[i], "' width='25' /><br>*", img.name,"*"))
}
Example image code:
"<img src='../pics/twitter-emojis/flag-cote-divoire_1f1e8-1f1ee.png'
width='100' /><br>*I. virginica*"
After that the labels can be changed and printed with markdown:
p + scale_x_discrete(name = NULL,
labels = rev(labels)) +
theme(axis.text.y = element_markdown(color = "black", size = 11))
