Colab Reconnect

ColabReconnect.js

// Interval time to check if runtime is disconnected
interval = 1000 * 60;

// Busy/Reconnect button top-right
reloadButton = document.querySelector('#connect > paper-button > span')

setInterval(() => {
    if (reloadButton.innerText == 'Reconnect') {
        reloadButton.click();
        console.log('Restarting');
    } else console.log('Keeps working');
}, interval);

Another possible solution which creates additional code cells:

function ClickConnect(){
console.log("Working"); 
document.querySelector("colab-toolbar-button#toolbar-add-text").click() 
}setInterval(ClickConnect,120000)

The current js snippet that works:

function ConnectButton(){
    console.log("Connect pushed"); 
    document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click() 
}
setInterval(ConnectButton,600000); //600 seconds
