Error when installing `@tableau/embedding-api` via `npm`

[velineurce]

The following error appears

error Couldn't find package "@tableau/[email protected]" required by "@tableau/[email protected]" on the "npm" registry.

When I am trying to install @tableau/embedding-api from npm

In docs https://help.tableau.com/current/api/embedding_api/en-us/docs/embedding_api_get.html#versions-of-the-tableau-embedding-api you don't mention anything about @tableau/api-external-contract-js
