## Not run: 
  # create the list of routes
  dynamic_routes <- list(
    route("other2", other_page(id = "other2")),
    route("other3", other_page(id = "other3"))
  )

  ui <- function() {
    router_ui(
      route("/", root_page(id = "root")),
      route("other", other_page(id = "other")),
      # then it's possible to inject a list of arguments into a function call using rlang::`!!!`
      !!!dynamic_routes,
      page_404 = page404(
        message404 = "Please check if you passed correct bookmark name!")
