Google Optimize installation on AMP page: Not verified

Question

We are trying to implement the amp-experiments on the amp-page and connect it with Google Optimize. We follow the instruction in this article — Measure AMP experiments with Optimize. But there is nothing about how to and should we to integrate Google optimize script inside amp-page.

As a result, we run an experiment with that message:

Is it ok for the experiments on amp pages? We can't add that script to amp page — <script src="https://www.googleoptimize.com/optimize.js?id=..., and we can't insert Google optimize via GTM — there is no way to do that in AMP GTM container

We did all as described in Measure AMP experiments with Optimize article, but it doesn't work — we don't see any active users or sessions in Google optimize dashboard
