How can I load a second app in a routing example

[sidviny]

Based on the examples, I have created an example that starts two Shiny apps. I also managed the application to run in its own window on my desktop using flaskwebgui, which also can do fastapi apps. That all works, but now I want to go to my page 2 using code and this I cannot find.

import getpass
from datetime import datetime

from fastapi import FastAPI
from flaskwebgui import FlaskUI
from shiny import App, reactive, render, ui

ui_one = ui.page_fluid(
    ui.output_text("clock"),
    ui.input_action_button("page_2", "Go to page2"),   # THIS IS WHERE I NEED ASSISTANCE

    title="A simple clock",
)


ui_two = ui.page_fluid(
    ui.output_text("greeting"),
    ui.input_action_button("page_1", "Go to page1"),

    title="A simple greeter",
)


def server(input, output, session):  # noqa
    @reactive.calc
    def time():
        reactive.invalidate_later(1)
        return datetime.now().strftime("%H:%M:%S on %B %d, %Y")

    @render.text
    def greeting():
        return f"Hello {getpass.getuser()}!"

    @render.text
    def clock():
        return f"It's currently {time()}."


app_one = App(ui_one, server)
app_two = App(ui_two, server)

app = FastAPI()

app.mount("/", app_one)
app.mount("/two", app_two)

FlaskUI(app=app, server="fastapi", width=800, height=600).run()

You can run this straight from the file, you do not need to use "shiny run". In PyCharm, I just select "Current file" and run it.
