Project Launcher: How to do 32bit built? Are Prerequisities included?

The project launcher seems to be locked on 64bit builds. I can not find a way to do 32 bit builds like I can do in the Packaging menu. Is this possible somehow?
Also, are the prerequisites included in builds done with the project launcher?

Basically, I was expecting that the project launcher offers/does the same thing as normal packaging, but with an asset list that allows patching/dlc-ing later on. But there seem option missing when comparing to the packaging menu in the project settings.

Figured it all out and and did also a tutorial.
