WatchOS Complications for App Launch Only

I have read the disconnected documentation for adding a "simple" complication that ONLY launches my app using the asset images I've created in various sizes for various families along with the ComplicationController code, but the complications never appear (with no errors).

I would like to support Watch Series 1 with OS 4.3 on up. There never seems to be one place where this simple, default function is documented.

What are the steps and code required to just launch a Watch app from a complication?
The documentation still says to select checkboxes for each family of complications BUT that is outdated for Xcode 12.3. I think I found only one line in thousands from WatchOS that, now, you need to add a key to Info.plist for the extension named ClockKit Complication - Supported Families and add Modular, Circular, etc. to that key.

No extra coding just template/glyphs in the right sizes for each sub-family.
