What is a binary and how do I find it, then how do I upload it

Super new to this. I don’t even know where to start with a binary. What, where and how are my 3 main questions.

Thanks!

The binary is the .aab file in the workspace you created for the Watchface project.

You build the project to create it
Pancake menu upper right corner of WFS
Project → Build
or F-10

You will need an Author Certificate (the Samsung one works) and a User Key you will need to create that.

See this documentation. It also links to the developer.android wearable documentation.
