Push notifications options

We would like to use push notifications to iPhone with our Mattermost installation.

However, there might be sensitive information so we are considering our options.

We are with Team Edition for now. Otherwise, the Full message content fetched from the server on receipt would be ideal.

The option to go with a self-hosted push-proxy service is not entirely clear to me when reading the the FAQ.

Can we use a self-hosted push-proxy without:

  1. compiling the push-proxy,
  2. our own Apple keys
  3. creating our own iOS app?

That is, simply just install the self-hosted push-proxy using helm chart and then enter its URL in System Console.
