How do I cook a specific folder from my game?

I’m using mod.io to publish mods for my game, and one of the requirements is to cook Unreal files before uploading the mods, but I’m not sure how to do that. This is what the mod.io documentation says:

“The easiest way to package/cook a mod into a pak file is to create a plugin that contains all the mod’s data. Then it is possible to invoke UnrealPak using the DLC cooker, such as via the Project Launcher that comes with every modern vanilla UE. Note that the mod would need to be cooked for every platform intended for release, unlike the Generic Data Type approach.”

However, I honestly don’t understand how to configure the Project Launcher to cook only the assets in the plugin. I’m not sure if the engine has changed since this documentation was made. I’m using Unreal 5.4. Can anyone help?
