r ggplot2 - custom text instead of the legend

Is it possible in ggplot2 to replace a legend with a custom text? I know about annotate but I do not want to write into a chart but next to it (or below it) - exactly where a legend would be and do it in a reasonably simple way.

E.g. in this simple chart

library(data.table)
library(ggplot2)
library(ggrepel)

id <- c(1:10) 
x1 <- sample(1:10, 10, replace=T)
x2 <- sample(1:10, 10, replace=T)
x3 <- sprintf("Point.%d",id)
df<-data.frame(id,x1,x2,x3)
dt<-data.table(df)
setkeyv(dt,c("id"))

p<-ggplot(data=dt,aes(x1,x2))+geom_point()+geom_text_repel(aes(label=x3))+
ggtitle("Graph")+xlab("X")+ylab("Y")+theme_bw()
p

I would like to write something (short) about the chart next to it. I am afraid that this might not be easily possible in ggplot2 since it is beyond its purpose - but would help me a lot.

this might be the easiest way,

gridExtra::grid.arrange(ggplot2::ggplot(), right = "this is a note")

enter image description here

by default text is rotated 90 degrees, to overwrite this use a textGrob explicitly,

gridExtra::grid.arrange(ggplot2::ggplot(), right = grid::textGrob("this is a note"))
