I need to integrate a new web application into an existing application written in angularJS. This new application will have to work both standalone (by entering the url of the new web app in a browser, without showing the old header with menus) and in integrated mode (imagine a header with menus showing below the contents of the old application and in one of these there's a link that will have to open the contents of the new application instead). The header bar with the other menus must be usable even after clicking on the link of the new application. Is it possible to do such a thing by developing the new application in react? Do you have other suggestions or links to understand how to do it

p.s. in order to stay logged in I was thinking of a SSO solution like keycloak
