Thanks for reaching out. It seems you haven't added tester's email to your project in the Google Cloud project(GCP).
To add an alpha tester, first, grant them Viewer/Editor access to your GCP. After they access the Developer Console and click the Test button, they'll be able to link and test your integration. Once the tester has completed these steps, your integration will be visible in their Google Home app, and they can start testing.
