Login Failure in NotionAPI Active User Settings to access Private Page

[fujiyamayusuke]

README says:

const notion = new NotionAPI({
  activeUser: process.env.NOTION_ACTIVE_USER,
  authToken: process.env.NOTION_TOKEN_V2
})

However, it didn't work resulting in an error like 'Error: Notion page not found xxx...'"
Instead, the following worked fine:

const notion = new NotionAPI({
  authToken: process.env.NOTION_TOKEN_V2
})

I'll look into it some more.
Thank you.
