Global Vue prop using Laravel/Inertia/Vue?

I'm using Laravel 10 / InertiaJS 1 / VueJS 3 with Composition API... I'm wondering if there is a way to create a global property instantiated within the createInertiaApp method call that is accessible globally in all components without additional imports or provide/injections in each component file? I have a set of data that is shared through the HandleInertiaRequests middleware, but I cannot seem to figure out how to get that data into some sort of globally-accessible state... For example, in my app.js file, I'm trying to capture the _app property passed in via Inertia and make it accessible in all components as $_app...

/* Imports excluded for brevity */
createInertiaApp({
	title:(title)=>`${title}`,
	resolve:async(name)=>(await import(`./pages/${name}.vue`).default,
	setup({el,App,props,plugin}){
		let appCreated=createApp({render:()=>h(App,props)})
			.use(plugin)
			.component('InertiaLink',Link)
			.component('InertiaHead',Head)
			.mixin({methods:{route}})
			.use(VueImgix,{
				domain:import.meta.env.VITE_IMGIX_DOMAIN,
				secureURLToken:import.meta.env.VITE_IMGIX_API_KEY,
				useHTTPS:true,defaultIxParams:{},
			})
			.use(ToastService);
        /* This is where I'm trying to create a globally-accessible property (unsuccessfully) */
		appCreated.config.globalProperties.$_app=props._app;
		return appCreated.mount(el);
	},
	progress:{color:'#4fb4d3'}
}).then();
