MainView not showing, instead there's a login page I did not create

I created a new project using spring initializer with Vaadin and Kotlin. I created an hello world view but when I run it doesn’t show up. Instead there’s a Sign In form that I can’t find anywhere in the code.

class StardriveApplication

fun main(args: Array<String>) {
class MainView : VerticalLayout() {
    init {
        add(H1("Hello World!"))

I think i figured it out, didn’t know spring security did this
