@angleprotocol/sdk requesting auth token while installing

[jac0x]

Dependencies cannot be installed due to error:

// yarn
error Error: https://npm.pkg.github.com/@angleprotocol%2fsdk: authentication token not provided

// npm
npm error code E401
npm error 401 Unauthorized - GET https://npm.pkg.github.com/@angleprotocol%2fsdk - authentication token not provided

Replacing sdk version with 3.0.129 (latest) doesn't work either.

Please, how can I solve this issue?
