How to communicate betweeen background and MAIN content script?

Hello! My design is like this: 1. In option page, set value. 2. In a specific websites, show its value (just simplified yeah) I'm struggle with finding the way to send value from option page to content script in MAIN area. Is there any recommended/standard way?

Oh, never mind. I successfully use storage api with removing below line:

export const config: PlasmoCSConfig = {
    matches: ["..."],
    world: "MAIN",
    run_at: "document_end"
}

export const config: PlasmoCSConfig = {
    matches: ["..."],
    world: "MAIN",
    run_at: "document_end"
}

but still wondering why I can modify DOM without this "MAIN" line
