Remove the lambda at the end of `context.renderChild(WelcomeWorkflow)`
The override for using `renderChild` on a child Workflow with `Nothing` as its output type does not have a lambda parameter

override fun render(
renderProps: Unit,
renderState: Unit,
context: RenderContext
): Any {
// Render a child workflow of type WelcomeWorkflow. When renderChild is called, the

return welcomeScreen
