How do I draw an arbitrary line in Chart.js?

Question

React

You need to draw lines on the chart and put text. I try like this:

useEffect(() => {
    // @ts-ignore
    var ctx = document.querySelector(".chartjs-render-monitor").getContext("2d");

    ctx.fillText('Рандомный текст', 12, 15);
  }, [])

But if I hover over the graph, then it will all be erased and will not appear again. How can I draw so that it stays and doesn't disappear?
