i want to take screenshot of django active page's elements. I research about selenium and playwright but they opening the pages on new browser. The page on which I want to take the screenshot has dynamic information and it is constantly changing, so it is not appropriate to take a screenshot by opening it on a new page. Each user will enter different information on the opened page and take a screenshot of the relevant element.

Here want i want to do;

1- Take screenshot of div with JS(OK)

2- Send POST Request to django url with JS to PYTHON(Need help -,- )

3- And send this image to slack(OK)

capturing div via html2canvas;

function capture() {
          html2canvas(document.getElementById("main"), {
              letterRendering: 1,
              allowTaint: true,
              useCORS: true,
          })
              .then(function (canvas) {
                  document.getElementById("result").src = canvas.toDataURL("image/png", 0.5);
              })
              .catch((e) => {
                  alert(e);
              });
      }
