const token = some_querystring_parser('access_token');
// use that token for all subsequent calls to api
cognitesdk.setBearerToken(token)
// Figure out how long til the token expires
const decodedToken = jwtDecode(token);
const msToExpiration =
decodedToken.expire_time * 1000 - new Date().getTime();
/* Call silentlogin function some time before it expires
repeat every time you get a new token
This injcts an iframe into your page, and gets the token from the a redirect in that frame
Pass in the url to an empty html file for fastest load times.
