I'm developing a Gmail addon. it's for a customer, so it can't be private (meaning it cannot be only available for my domain).
I created the App Script project and linked to a standard GCP Project, on which I'm now configuring the G Suite marketplace SDK with oauth scopes etc.
In the Configuration page I've selected "Public" Visibility and it asked me to fill a "Gmail Add-ons Submission Information". I filled it with all the information required more than one week ago but so far I haven't received any reply, not even an automatic one to let me understand it was taken in charge.
Has anyone ever received a feedback from Google after filling this form ? Is there a way to make contact with Googlers on this? I have opened a ticket on GCP but they replied it's not their scope, so I'm going to open another for G Suite...
Please note that I don't want right now to actually publish the addon, I just need to save my Marketplace SDK Configuration to be able to try the addon installation with the "Integrate with Google" button that appears once that you save the configuration.
