How to pass context between tabs BottomNavigation?

[kaifaty]

I spend much time to figure out this question, but I can't.
My files:
app-root.xml

<BottomNavigation loaded = "initApp" >
    <TabStrip>
        <TabStripItem class="navigation__item">
            <Label text="Home" />
            <Image src="font://&#xf015;" class="fas t-36" />
        </TabStripItem>
    </TabStrip>
    <TabContentItem >
        <Frame defaultPage="home/home-items-page"/>
    </TabContentItem>
</BottomNavigation>

app-root.ts

import {NavigatedData, Page} from "@nativescript/core";

export function initApp(args: NavigatedData) {
    const page = <Page>args.object;
    args.context = {
        title: "MyContext"
    }
}

home/home-items-page.xml

<Page navigatingTo="onNavigatingTo"
    xmlns="http://schemas.nativescript.org/tns.xsd">
</Page>

home/home-items-page.ts

import {NavigatedData, Page} from "@nativescript/core";

export function onNavigatingTo(args: NavigatedData) {
    const page = <Page>args.object;
    console.dir("=>>> context: ", args.context) //undefined
}

How I can get access to context {title: "MyContext"} in home/home-items-page.ts?
