How to navigate from one NavGraph to another NavGraph?

I made a custom NavGraph for the Sign Up process:

@RootNavGraph
@NavGraph()
annotation class SignUpNavGraph(
    val start: Boolean = false
)

Other composable destinations are making use of the RootNavGraph. I am trying to navigate from:

@SignUpNavGraph()
@Destination
@Composable
fun SignUpTwoScreen(
    navigator: DestinationsNavigator,
    scaffoldState: ScaffoldState
) ..

to

@Destination(
    navArgsDelegate = VerifyScreenNavArgs::class
)
@Composable
fun VerifyScreen(
    navigator: DestinationsNavigator,
    verifyEmailViewModel: VerifyEmailViewModel = hiltViewModel()
) ..

with

 navigator.navigate(
     VerifyScreenDestination(viewModel.email, viewModel.password)
 )
 navigator.popBackStack()

It seems that I cannot navigate from the SignUpTwoScreen to the VerifyScreen.

I am using this awesome open-source project Compose Destinations. Documentation can be found here
