package completions not active in devbox shells (e.g. kubectl )

[gberche-orange]

What happened?

The kubectl nix package seems to have builtin completion enabled, see https://github.com/NixOS/nixpkgs/blob/d04d8548aed39902419f14a8537006426dc1e4fa/pkgs/by-name/ku/kubectl/package.nix#L24-L29

However, following a devbox shell, the kubectl completion is not active.

I'm running plain fresh ubuntu 24.0.4 with bash shell.

Same problem with all packages, e.g. kind also supporting completion https://github.com/NixOS/nixpkgs/blob/d04d8548aed39902419f14a8537006426dc1e4fa/pkgs/by-name/ki/kind/package.nix#L41-L46
