Reference app for how to use packages together #43
Description
Is your feature request related to a problem? Please describe.
I'd like to see how to use all of these packages together in an example app.
Describe the solution you'd like
Some type of code example we can keep up to date (maybe also use as upstream/consumer type FVT).
Potentially also a generator I can use to spin up my own awesome Slack toolbox app quickly and easily.
