How can I integrate a rootless containers api for an embedded containerd client app?

[pcbuildpluscoding]

Hi,
I've made a containerd client app and wanted to integrate rootless for the containers and tasks that I create. For development testing, I installed rootless by running containerd-rootless-setuptool.sh on my ubuntu pc and nerdctl works well.

I tried to convert the nerctl/pkg/rootlessutil/appNeedsRootlessParentMain function for my api service program. It works as far as generating a network namespace that my client and service run inside. I can create a container, but my program hangs when I create a task. Is there a better way to integrate a rootless environment? Is there a rootless api package for embedding a rootless environment?
