interestCohort on third party sites

[nikoplusx]

Reading the docs here and here. As well the docs for how to be part of the origin trials here I

1. Registered my domain on the origin trials - let's say https://example.io - yes it is https

2. I used the following snippet to retrieve the interest cohort on a few pages

   function addTrialToken(tokenContents) {
     const tokenElement = document.createElement('meta');
     tokenElement.httpEquiv = 'origin-trial';
     tokenElement.content = tokenContents;
     document.head.appendChild(tokenElement);
   }
   
   if(isChrome){
         addTrialToken('<token I received from the origin trials>');
   
         document.interestCohort().then((cohortInfo) => {
           const events = [];
           events.push({ cohortId: cohortInfo.id, cohortVersion: cohortInfo.version });
         });
    }

My problem is that I cannot get the interestCohort method to work and I am always getting a Uncaught TypeError: document.interestCohort is not a function. What am I doing wrong here?

If my registered domain is https://example.io, I am trying to access the cohort from https://example.io/other.html

The origin trial is only running right now for a fraction of people in Chrome Beta. If you want to start up your own copy of Chrome with the API available, there are instructions at https://developer.chrome.com/blog/floc/#enable-floc-with-browser-flags.
