What kind of feature are you missing? Where do you notice a shortcoming of PTB?

Documentation on how to

• run multiple PTB bots in the same python process
• run PTB side-by-side with other asyncio frameworks in the same python process

is currently rather scarse.

Describe the solution you'd like

A section on the "Frequently requested design patterns" or even a standalone wiki page with some tips on these. Importants points are

• why App.run_{polling, webhook} are not suitable in these cases
• Detailing which order to call App.{initialize, start, stop, shutdown} & Updater.start_{polling, webhook} in
• noting that cancelling pending tasks should be done after the app has shut down (see first bullet point in [BUG] Application gets stuck while manually stopping in async environment #3397 (comment))
• Some notes along the lines "there are many different design patterns for long-running asyncio processes, and there is probably not one right way for your use case"

Describe alternatives you've considered

No response

Additional context

• we already have the Tip: thingies in the docstrings of App.run_{polling, webhook}, but that's apparently not enough
• customwebhookbot showcases this to some extend but the "keep the process alive" part is conveniently covered by uvicorn and Updater is not included
• There were several threads in the user-group where these topics were touched
• [BUG] Application gets stuck while manually stopping in async environment #3397
