To silence a remote notification, you must set the apns-push-type header field to alert when you send the notification to the APNS server. Otherwise, the system always displays the notification banner to the user.
nb: the client-part was just merged with https://github.com/deltachat/deltachat-ios/pull/2124 and compliance seems to be set, so this single header line might be the last bit to finally make silencing working :)
