Importing NPM packages with `npm:` where package has `@` in the name

I want to import the package

@hono/zod-openapi

@hono/zod-openapi

, version

0.30

0.30

I tried to add to my

deno.json

deno.json

like so:

{
  "imports": {
    "@hono/zod-openapi": "npm:@hono/zod-openapi@0.3.0",
  }
}

{
  "imports": {
    "@hono/zod-openapi": "npm:@hono/zod-openapi@0.3.0",
  }
}

but it doesn't work:

error: Could not resolve 'npm:@hono/zod-openapi@0.3.0'.

Caused by:
    not found

error: Could not resolve 'npm:@hono/zod-openapi@0.3.0'.

Caused by:
    not found

I also tried: removing the leading

and tried

@hono@0.3.0/zod-openapi

@hono@0.3.0/zod-openapi

but those don't work either.
