Add a title to gprofiler2 gosttable in R - r

Question

Hello I'm a new bioinformatician so bear with me please!
I'm using the gprofiler2 to run GO/KEGG analysis in R using emacs/ess and I want to add a title to the table it offers:
publish_gosttable(gostres, highlight_terms = gostres$result[c(1:2,10,120),],
use_colors = TRUE,
show_columns = c("source", "term_name", "term_size", "intersection_size"),
filename = NULL)
I have tried the title(), tab_header() function but I can't seem to be able to add a title. My question is if there is some other function or package that would allow me to add it instead of having to do it manually.
The code so far
GOresult <- gost(
geneid1up$gene,
organism = "hsapiens",
ordered_query = FALSE,
multi_query = FALSE,
significant = TRUE,
exclude_iea = FALSE,
measure_underrepresentation = FALSE,
evcodes = FALSE,
user_threshold = 0.05,
correction_method = "gSCS",
domain_scope = "annotated",
custom_bg = NULL,
numeric_ns = "",
sources = c("GO:BP","GO:MF","GO:CC","KEGG"),
as_short_link = FALSE)
GOresult1 <- as.data.frame(GOresult$result)
GOresult1$minuslog10pval <- -log10(GOresult1$p_value)
names(GOresult1)[15] <- "-log10(pval)"
GOresult2 <- GOresult1[order(GOresult1$p_value, decreasing=F),]
plot1 <- publish_gosttable(GOresult2, highlight_terms = GOresult2[c(1:20),],
use_colors = FALSE,
show_columns = c("source", "term_name", "term_size", "intersection_size","-log10(pval)"),
filename = NULL)

Does this do the job?
library(gprofiler2)
library(ggplot2)
gostres <- gost(query = c("X:1000:1000000", "rs17396340", "GO:0005005", "ENSG00000156103", "NLRP1"),
organism = "hsapiens", ordered_query = FALSE,
multi_query = FALSE, significant = TRUE, exclude_iea = FALSE,
measure_underrepresentation = FALSE, evcodes = FALSE,
user_threshold = 0.05, correction_method = "g_SCS",
domain_scope = "annotated", custom_bg = NULL,
numeric_ns = "", sources = NULL, as_short_link = FALSE)
publish_gosttable(gostres, highlight_terms = gostres$result[c(1:2,10,120),],
use_colors = TRUE,
show_columns = c("source", "term_name", "term_size", "intersection_size"),
filename = NULL)+
ggtitle('Your Title')
Result:
The trick is that the plot is a ggplot objet. Therefore you can add the title using +ggtitle('Your Title') after your plot code (as in my example)
