使用 JSExecutor 从另一个文档中获取文档

Question

I am trying to get an element from a page and click on it. But I came across the #document tag. My last step with this problem:

var doc = (OpenQA.Selenium.Remote.RemoteWebElement)_driver.ExecuteQuery("return window.document");
doc.FindElementByXPath("//span[text()='Принять']").Click();

But answer is:

 OpenQA.Selenium.NoSuchElementException: "no such element: Unable to locate element:

{"method":"xpath","selector":"//span[text()='Принять']"} (Session info: chrome=80.0.3987.132)"

If i try to do it in browser - all is ok. Only one match.

Please help with it

Find the way. Thanks to @itronic1990 .

    Driver.SwitchTo().Frame(0);
    var doc = (OpenQA.Selenium.Remote.RemoteWebElement)_driver.ExecuteQuery(
        "return document");
    doc.FindElementByXPath("//button[./span[text()='Принять']]").Click();
