Unable to implement third-party Google Calendar Conferencing Add-on

Question

I'm working on the Google Calendar conferencing add-ons implementation and found some problems. I follow the documentation to execute the sample code, but it does not work as expected.

From my point of view, my manifest file is complete, but when I try to publish the Calendar conferencing add-on from the 'Deploy from manifest' link, it opens my google calendar, but it does not show my conferencing as it shows the Hangout and Uberconference for example.

I was expecting some log messages on my entry point function in Stackdriver, but even that is not working. Do you have any clues where I should start my investigation? Below is my manifest file and also my createConference function definition.

You need to be whitelisted to develop and debug google calendar plugins by Google.

Edit: At that point in time, you needed to have a contact within google that whitelisted you, not sure if this is still the case. Did not work on this for a long time. Not sure how to get in contact with them, I never was in any direct contact myself.
