busyIndicatorOptions: use color of custom svg

[rwaaijman]

I would like to use a custom svg to as busyindicator, but this custom svg contains multiple colors. Is it possible to use the custom colors, instead of a standard color?

library(bslib)
library(shiny)

ui <- page_fillable(
  useBusyIndicators(),
  busyIndicatorOptions(spinner_type = "spinner.svg", spinner_size = "150px"),
  # busyIndicatorOptions(spinner_type = "bars"),
  plotOutput("plot")
)

server <- function(input, output, session) {
  output$plot <- renderPlot({
    Sys.sleep(5)
    plot(x = rnorm(100), y = rnorm(100))
  })
}

shinyApp(ui, server)

and the svg (spinner.svg):
