R 更改默认系列1以更改名称

我有一个柱形图，我想修改列内的名称.问题是，我不想要静态名称，也不想要默认名称(系列1)

代码如下:

df <-
  structure(
    list(
      CCAA = c(
        "ANDALUCÍA",
        "CEUTA",
        "COMUNITAT VALENCIANA",
        "CASTILLA-LA MANCHA",
        "EXTREMADURA",
        "CASTILLA Y LEÓN"
      ),
      TOTAL = c(27,
                14, 4, 2, 2, 1),
      COLOR = c(
        "#E30613",
        "#E30614",
        "#E30615",
        "#E30616",
        "#E30617",
        "#E30618"
      ),
      BANDERAS = c(
        "FLAG 1",
        "FLAG 2",
        "FLAG 3",
        "FLAG 4",
        "FLAG 5",
        "FLAG 6"
      )
    ),
    class = c("tbl_df", "tbl", "data.frame"),
    row.names = c(NA,-6L)
  )

海查特地块的密码是:

grafico <- highchart() %>%
    hc_chart(type = 'column') %>%
    hc_tooltip(table=TRUE) %>%
    hc_xAxis(categories = df$BANDERAS) %>%
    hc_colors(color=df$COLOR) %>%
    hc_exporting(enabled = TRUE) %>%
    hc_legend(enabled=FALSE) %>%
    hc_plotOptions(series = list(animation = FALSE)) %>% 
    hc_add_series(df$TOTAL, dataLabels = list(enabled = TRUE, format='<span style="fontfamily: sans-serif">{point.y}</span>'), colorByPoint=TRUE)

我该如何在系列1中放置CCAA的名称，而不是默认的名称，并在x轴上放置不同的BANDERA名称？
