How to set initial url upon application startup

Question

I have a pretty simple Vaadin Flow project for a college course setup with working login functionalities.

I know that the project automatically opens up to localhost:8080 in my default browser, but I am trying to get it to initially open to my login page to avoid getting routed to an error page.

I get around this to access my project by simply adding '/login' after the URL, but I was wondering where in my project I can have it open to 'localhost:8080/login' upon startup if this is even possible. Thanks!
