How to wait for an element is not attached in DOM ?

stalenessOf() in protractor ?

• stalenessOf() will verify the element is not present in DOM in given time.
• stalenessOf() is just opposite of presenceOf() in protractor.

Please check below code script:

describe('Protractor - waits - stalenessOf()', function () {
    beforeAll(async function () {
        await browser.get("https://keeplearners.blogspot.com/2018/03/Angular-elements.html");
    });
    it('Code script to use waits - stalenessOf() in protractor', async function () {
        var EC = protractor.ExpectedConditions;
        var dombutton = element(by.css("input#not-displayingg"));
        await browser.wait(EC.stalenessOf(dombutton, 5000, "Element appeared in the DOM in given time"));
        await console.log("Verified element is not present in DOM");
    });
});

The web element(dombutton) we declared in above script is not present web page
