npx, deno run and esm.sh all result in "No sub command specified"

[LazerJesus]

generator docs {
  provider = "deno run -A npm:prisma-docs-generator"
  provider = "npx prisma-docs-generator"
}

Neither of these works, both producing the same output:

  Documentation reference generator for Prisma Schema

  Usage
  $ prisma-docs-generator [command] [flags]

  Options
    -v Prints out the version number

    serve
      --port -p   Specify the port from which this cli should serve the docs
  

Error: Generator "npx prisma-docs-generator" failed:

No sub command was specified

I read the code, and the problem is that bin/cli is called for some reason.
I just used this package for testing, so not critical for me. just a heads up.

both deno run and npx work with for example the kysely generator.
