Copy the javascript code and paste in the browser console after opening an inbox in whatsapp web.

Code:

let b = setInterval(() => {
    let hora = new Date;
    let a = document.getElementsByClassName("_2YPr_ i0jNr selectable-text copyable-text");
    if (a.length == 0) {
        console.log("off");
    } else if (a[0].title == "online") {
        console.log(`online ${hora.getHours()}:${hora.getMinutes()}`);
    }else{
        console.log("undefined");

}, 3000)
b;

❗🔺 Considerations

• The code is intended for parents to monitor their children when they are online (especially during the night).
• Just copy and paste into the console, after opening the chat, and leave it running. To do this, you must keep the computer turned on and the whatsapp web open.
