How do I use the MODULE.bazel mechanism to use flakes?

How do I convert this WORKSPACE style to MODULE.bazel style?

WORKSPACE.bzlmod

http_archive(
    name = "io_tweag_rules_nixpkgs",
    sha256 = "1adb04dc0416915fef427757f4272c4f7dacefeceeefc50f683aec7f7e9b787a",
    strip_prefix = "rules_nixpkgs-0.12.0",
    urls = ["https://github.com/tweag/rules_nixpkgs/releases/download/v0.12.0/rules_nixpkgs-0.12.0.tar.gz"],
)

load("@io_tweag_rules_nixpkgs//nixpkgs:repositories.bzl", "rules_nixpkgs_dependencies")
rules_nixpkgs_dependencies()

load("@io_tweag_rules_nixpkgs//nixpkgs:nixpkgs.bzl", "nixpkgs_cc_configure", "nixpkgs_flake_package", "nixpkgs_git_repository", "nixpkgs_package", "nixpkgs_python_configure")

nixpkgs_flake_package(
    name = "awscli",
    nix_flake_file = "//tools/aws:flake.nix",
    nix_flake_lock_file = "//tools/aws:flake.lock",
    package = "awscli2",
)

Later, I have a BUILD.bazel file that looks like this:

genrule(
    name = "aws",
    srcs = ["@awscli//:bin/aws"],
    outs = ["awscli/aws"],
    executable = True,
    cmd = "cp $(<) $@",
)

Having trouble figuring out how to bzlmod-ify this.
