Print a circle above every 15:29 minute

1

Can somebody adjust this script so that it prints an orange circle above every 15:29 minute?

const predef = require("./tools/predef");
const { du } = require("./tools/graphics");

class SingleBarDot {
  init() {}

  map(d, i, history) {
    let items = [];
    const data = history.data;
    const targetIndex = data.length - 30; // last 30th bar

    if (i === targetIndex) {
      items.push({
        tag: "Shapes",
        key: "dot",
        primitives: [
          {
            tag: "Rectangle",
            position: {
              x: du(d.index()),
              y: du(Math.min(d.open(), d.close())) // top of the candle body
            },
            size: {
              width: du(1),               // small width = single bar
              height: du(Math.abs(d.close() - d.open())) // candle body height
            }
          }
        ],
        fillStyle: {
          color: "orange",
          opacity: 100
        }
      });
    }

    return { graphics: { items } };
  }
}
