The problem is that I don’t know how to position the ticks (numbers from 1 to 5) between the grid lines. Currently it is showing above the grid lines:

Here is the javascript code:

const ctx = document.getElementById("myChart");

new Chart(ctx, {
  type: "radar",
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange", "Turquesa"],
    datasets: [
      {
        data: [4, 3.5, 2, 5, 4.5, 4, 2],
        borderWidth: 1,
        backgroundColor: "#ECAE4880",
        borderColor: "#FBDDAD",
        color: "#f00"
      }
    ]
  },
  options: {
    elements: {
      point: {
        pointStyle: false
      }
    },
    scales: {
      r: {
        min: 0,
        max: 5,
        backgroundColor: "#FDF7EC",
        ticks: {
          backdropPadding: {
            x: 16,
            y: 16
          },
          z: 10,
          backdropColor: "transparent",
          color: "red",
          backgroundColor: "black",
          stepSize: 1
        },
        grid: {
          color: "#EA910B",
          backgroundColor: "red"
        },
        angleLines: {
          color: "transparent",
          // borderDash: 0
        }
        // angleLines: {
        //   display: false
        // },
        // suggestedMin: 50,
        // suggestedMax: 100
      }
    },
    plugins: {
      legend: {
        display: false
      },
      title: {
        display: false
      },
      subtitle: {
        display: false
      }
    }
  }
  // plugins: [
  //   {
  //     id: "centerTick",
  //     afterDraw: (chart, args, opts) => {
  //       const { ctx } = chart;
  //       ctx.fillStyle = opts.color || Chart.defaults.color;
  //       ctx.fillText(
  //         chart.scales.r.min,
  //         chart.scales.r.xCenter -
  //           ctx.measureText(chart.scales.r.min).width / 2,
  //         chart.scales.r.yCenter
  //       );
  //     }
  //   }
  // ]
});

I tried setting plugin (commented code), but it does not work:

I expect the ticks be like this image below:
