Maintaining Google Font when converting ggplot figure to plotly

[Juliana_S]

Hello, I'm trying to figure out how to maintain Google Font used in a ggplot figure when converting the figure to a plotly object. Here is my code:

library(ggplot2)
library(plotly)
library(tidyverse)
library(showtext)
library(sysfonts)

font_add_google("Open Sans", "open")

showtext_auto()

data <- iris
barChart <-
  data %>% ggplot(aes(
    x = Sepal.Width,
    y = Sepal.Length,
    fill = Species,
  )) + geom_bar(stat = "identity") +
  theme_gray(base_family = "open") 

p <- ggplotly(barChart)

The font does not persist once the figure is converted to plotly object. TIA for any help or suggestions.
