How can I use deno to install Buf SDKs through NPM?

TLDR

TLDR; How can I replicate these commands using Deno?

npm config set @buf:registry https://buf.build/gen/npm/v1/
npm install @buf/wcygan_flock.bufbuild_es@latest

More information

I'd like to use the SDKs from https://buf.build/wcygan/flock/sdks, which are hosted here: https://buf.build/gen/npm/v1/@buf%2fwcygan_flock.bufbuild_es

I understand that https://docs.deno.com/runtime/fundamentals/node/#private-registries specifies to use .npmrc, which I am trying like this:

@buf:registry=https://buf.build/gen/npm/v1/

But now I'm unsure of how to process, I've tried these ideas but they don't appear to work:

"imports": {
  "@buf/wcygan_flock.bufbuild_es": "npm:@buf/[email protected]",
  "@buf/wcygan_flock.bufbuild_es": "npm:@buf/wcygan_flock.bufbuild_es@latest"
}

I'm also not sure of how to do it with deno add:

deno add npm:@buf/wcygan_flock.bufbuild_es@latest
error: npm:@buf/wcygan_flock.bufbuild_es was not found.
