If my target pod has multiple contianers?

If my target pod has multiple contianers?
When I execute kubectl debug target_pod, I found it will talk with the first container.
But If my target pod has two containers, what should I do if I want to talk with the second/another contaienr?
Thanks

The issue concerns selecting a non-first container when running kubectl debug against a target pod, but it names no files, tests, or implementation entry point. The repository is marked no longer maintained; investigate the linked successor project first and define the expected command behavior there before considering implementation.
