I get the name of a screen like this :

const initialScreen =
    currentStep === ESteps.ONBOARDING_COMPLETE
      ? 'CheckSteps'
      : (currentStep as keyof RootStackParamList);

and I wanted to implement it then as initialRoutename :

<SignUpStack.Navigator initialRouteName={initialScreen} headerMode="screen">
      <SignUpStack.Screen
        name="CheckSteps"
        component={CheckSteps}
        options={{ 
    ...  

I retrieve the name of the screen, but it absolutely does not redirect me ... You would know why or how to do it?
