How can I host APIs instead of running shiny apps in docker containers and serve them through ShinyProxy Server?

Is there a way to provide APIs in docker container and as a user logs in they could have access to a new docker instance and use the APIs in that container?
I know that with plumber I can create the APIs in R and host them on an address. How it can be used on a docker and be hosted in ShinyProxy I don’t know how to do it?

Any idea dear ShinyProxy Community? Thanks for your help in Advance.

If you are using plumber, you can also run it inside a docker container - see https://www.rplumber.io/articles/hosting.html#docker - and then include it as an app on shinyproxy
