Having trouble using Satisfies with IE 11

[ryanbelisle]

I'm trying to use the isValidBrowser code example to return true or false if IE11 is detected. However, it always returns undefined.

const Bowser = require("bowser"); // CommonJS

const browser = Bowser.getParser(window.navigator.userAgent);

const isValidBrowser = browser.satisfies({
  // declare browsers per OS
  windows: {
    ie: "11"
  }
  // chrome: ">89",
});
console.log(browser.getBrowser());
console.log(isValidBrowser);

Am I missing something?

Thanks in advance!
