#' into a list of arguments. It is primarily used to facilitate the passing of
#' additional arguments from the Shiny UI to internal functions within the app.
#'
#' @param arg_str A character string representing R arguments.
#'
#' @return A list containing the arguments represented by \code{arg_str}. If
#'   \code{arg_str} is not a valid representation of R arguments, the function
#'   will throw an error.
