The reason all the documents in your application is provided to the other owners is because any interested party can make a submission regarding your application.
You needed to include the information you did to make a comprehensive submission, so don’t worry about it.
In terms of the adjudication process, you don’t have to do anything now – a decision is made “on the papers”. That is, the adjudicator reads the submissions received and makes a decision based on those. All you can do now is wait. The only exception would be is if someone made a submission more than 3 days before closing date, in which case you would be provided with it and you could make a further submission.
It can take quite a while for a decision, we had one recently and it was over 2 months.
