Create monitor app with await asyncio.create_subprocess_shell

[doctorx]

I tried to run the application for monitoring Fastapi debug server. I want to catch stdout output from several debug servers.

But catch an error because method render is not async.

Catch error because method render does not async.
Could be helped to find the example of an idea of how to do it with textual?

import asyncio
from asyncio.subprocess import PIPE

import logging
from rich.logging import RichHandler

from textual.app import App
from textual.widget import Widget

from textual.widgets import Header
from rich.panel import Panel


FORMAT = "%(message)s"
logging.basicConfig(
    level="NOTSET", format=FORMAT, datefmt="[%X]", handlers=[RichHandler()]
)

log = logging.getLogger("rich")

class ServerLogs(Widget):

    async def on_mount(self):
        self.set_interval(1, self.refresh)
        self.process = await asyncio.create_subprocess_shell("uvicorn server:app --reload", stdout=PIPE, stderr=PIPE)

    def render(self):
        line_log = self.process.stdout.readline()
        return Panel("sss")


class MonitorApp(App):
    async def on_mount(self):
        await self.view.dock(Header())
        await self.view.dock(ServerLogs())


MonitorApp.run()
