Apps api usage - User Installations API

Hi all!
Im trying to use the /apps API and i don’t understand how to use /user/installations request (Apps - GitHub Docs).

I call this request using a token i got from /app/installations/{installation_id}/access_tokens
(/Apps - GitHub Docs)
And i get back this response

{
“message”: “Resource not accessible by integration”,
“documentation_url”: …
}

What do you suggest?

Thanks!
