Telling Rider to attach docker debugger if project is used by another dockerfile

Hey. Here is my directory structure:

- Project.sln

- SynchronizeSftpUsers (.NET Project)

- .NET Project 2

   - Dockerfile

- .NET Project 3

   - Dockerfile

- SftpServer (atmoz/sftp)

   -  Dockerfile

- docker-compose.yml

I have this niche case where I need my SftpServer's user.conf file to be refreshed every minute or so, synchronizing users against other database. Normally, I would need to manually update users.conf file and then restart entire container and I need it to happen in real time without restarts, so I created SynchronizeSftpUsers that updates this file and refreshes the server cache. Of course it could be done better but I'm learning and that's what I have so far.

The issue is that my docker compose takes into account .NET Project 2, .NET Project 3 and SftpServer's dockerfiles. I added this docker compose to Rider's configurations and I can successfully debug .NET Project 2 and .NET Project 3. My SftpServer's dockerfile looks like this:

EXPOSE 22

ENTRYPOINT ["/entrypoint"]

This results in SynchronizeSftpUsers running successfully in the background, however I have no idea how can I debug this process inside the container. I don't know how to tell Rider to look for this process inside of this container, because now it's not explicit and it does not work. Can this be done and if not, then how can I do this in a better way?
