Use HTML in sweetalert button

Question

Is there any chance to not only use html in the text but in the button of sendweetalert or confirmsweetalert in the shinyWidgets package?

library(shiny)
library(shinyWidgets)

ui <- fluidPage(
  tags$h1("Confirm sweet alert"),
  actionButton(
    inputId = "launch1",
    label = "Confirmation"
  ),
  verbatimTextOutput(outputId = "res1"),
  tags$br(),
  actionButton(
    inputId = "launch2",
    label = "Sweetalert"
  ),
  verbatimTextOutput(outputId = "res2")
)

server <- function(input, output, session) {

  observeEvent(input$launch1, {
    confirmSweetAlert(
      session,
      inputId = "confirm",
      btn_labels = HTML("<a href='https://google.de'>Link</a>"),
      title = "confirmation",
      html = T
    )
  })
  output$res1 <- renderPrint(input$confirm)

  observeEvent(input$launch2, {
    sendSweetAlert(
      session,
      title = "sweetalert",
      html = T,
      btn_labels = HTML("<a href='https://google.de'>Link</a>")
    )
  })
}

shinyApp(ui = ui, server = server)
