What are the essentials of storing information in project.json?

[2001733]

I am attempting to replicate the functionality implemented in obviousAlexc's penPlus that stores information in project.json for my own extension. However, despite several attempts, I still haven't grasped the essence of how it works—all my efforts have ended in failure. Could someone please help me? I would greatly appreciate your assistance. Thank you in advance.

According to something I understood from reading about extensions, you need your extension to be registered as an internal object. But I can't tell you. I hope you find a solution.

if (!runtime.extensionStorage[EXTENSION ID HERE!!!]) {
    runtime.extensionStorage[EXTENSION ID HERE!!!] = Object.create(null);
}

Then edit runtime.extensionStorage[EXTENSION ID HERE!!!]'s properties to save stuff.
