R Alignment of actionButton to the bottom-CodePudding

I would like to create an actionButton in the sidebar of a flexdashboard.
However, I would like to align this button at the bottom. This should hover a few pixels above the bottom. What do I have to change in the style-command to achieve this?

Many thanks in advance!

observeEvent(input$show, {
      showModal(modalDialog(
        title = "Send me a message",
        "Text Text Text",
        easyClose = TRUE,
        footer = modalButton("Schließen")
      ))
