AmChart not showing tooltip on bullets.

HTML:

<script src="//www.amcharts.com/lib/4/core.js"></script>
<script src="//www.amcharts.com/lib/4/charts.js"></script>
<div id="chartdiv"></div>

CSS

body {
  font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
}

#chartdiv {
  width: 100%;
  height: 300px;
}

JS:

var chart = am4core.create("chartdiv", am4charts.XYChart);

chart.dataSource.url = "https://fapi.binance.com/futures/data/globalLongShortAccountRatio?symbol=BTCUSDT&period=5m";

var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "timestamp";

var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());

var series1 = chart.series.push(new am4charts.LineSeries());
series1.dataFields.valueY = "shortAccount";
series1.dataFields.categoryX = "timestamp";
series1.name = "shortAccount";
series1.strokeWidth = 3;
series1.tensionX = 0.7;
series1.bullets.push(new am4charts.CircleBullet());
series1.tooltipText = "{categoryX}: [bold]{valueY}[/]";

var series2 = chart.series.push(new am4charts.LineSeries());
series2.dataFields.valueY = "longShortRatio";
series2.dataFields.categoryX = "timestamp";
series2.name = "longShortRatio";
series2.strokeWidth = 3;
series2.tensionX = 0.7;
series2.bullets.push(new am4charts.CircleBullet());
series2.tooltipText = "{categoryX}: [bold]{valueY}[/]";

var series3 = chart.series.push(new am4charts.LineSeries());
series3.dataFields.valueY = "longAccount";
series3.dataFields.categoryX = "timestamp";
series3.name = "longAccount";
series3.strokeWidth = 3;
series3.tensionX = 0.7;
series3.bullets.push(new am4charts.CircleBullet());
series2.tooltipText = "{categoryX}: [bold]{valueY}[/]";

chart.legend = new am4charts.Legend();

I also want to show current time -(minus) 5 min on Xaxis.

Like if current time is 3:45PM it should show 3:40PM, Is it possible?

Thank you so much for your help.
