Can't embed trelliscope to a rmarkdown

[Valanis21]

I can't embed a trelliscope to a markdown, it appears only a space in blank (I am using the pokemon example for practice)
The code is the following:

title: "Pokemon"
author: "Victor Alanis"
date: "22/1/2021"
output:
html_document:
self_contained: no

knitr::opts_chunk$set(echo = TRUE)
knitr::opts_chunk$set(message = FALSE, warning = FALSE) #suppress ggplot2 warnings
library(trelliscopejs)
library(dplyr)
library(ggplot2)
library(tidyr)
library(rbokeh)

pok <-
  read.csv("https://raw.githubusercontent.com/hafen/pokRdex/master/pokRdex_mod.csv") %>%
  mutate_at(vars(matches("_id$")), as.character)


pok %>%
  mutate(panel = img_panel(url_image)) %>%
  trelliscope("pokemon", nrow = 3, ncol = 6,
              state = list(labels = c("pokemon", "pokedex","id"),sort=list(pokemon="asc")),path="Pokemon",self_contained=TRUE)

And the output is the following
