Changing the link in the Showcase

Hi There!
I have had recently a problem signing an update to my Ionic2 app on the Google Play Store, so i had to hide the old app and publish a new one (this time I saved the keystore properly).
My problem now is that my old app is still linked to in the Ionic Showcase, but the link doesn’t work anymore of course. Is there an email to which i can write to have the link fixed?
Thank you very much in advance.
