Page.open in Vaadin 10 ?

In Vaadin 8 there was method Page.open. What is replacement in Vaadin 10 ?

Will [UI#navigate]
(https://vaadin.com/api/platform/11.0.1/com/vaadin/flow/component/UI.html#navigate-java.lang.String-com.vaadin.flow.router.QueryParameters-) help you to solve the issue?

No. I navigate to external url.
My solution is:
currentPage.executeJavaScript("window.location = '$uri';")
