electron. Redirect after authorization?

Question

Node.js

In general, having broken my head with registration and authorization in electrone, I came to the following:
1) I created a separate project in which I implemented the simplest API for registration and authorization.
2) I created a window in the electron, in it there is a registration and authorization form. There are no problems with registration ...
3) There are a couple of questions about authorization.
Authorization is obtained, I get a session in an electronic application, but that's it ...

I can't figure out how to move on. That is, there is a session in the application, but what can I do so that the authorization window closes and the main content window appears, so to speak?
Many thanks in advance for your help.
