Updating App on Store

[GigaSora]

For apps already on the store:

To update it, do I just push a new build to the store channel? Or do I have to resubmit and run it through the review process again?

For anyone looking for the answer: You just push it to the store channel and it becomes available immediately. If you want to change other aspects about your app, like description, asset images, etc. You submit for review again.
