How to retrieve documents in firestore order with timestamp with React

[anoonoll]

I wrote the following code.

const salons = query(collection(db, "user"), orderBy('', "desc"), limit(5))
const querySnapshot = await getDocs(salons)
await querySnapshot.forEach((doc) => {
    console.log(new Date(doc._document.version.timestamp.seconds * 1000).toString())
    //processing
})

I want to sort the orderby by "doc._document.version.timestamp.seconds" which is displayed in console.log.

But I don't know how to do it.
This date is automatically registered by firestore, so the position of the value is different.
Does anyone know how I can sort it?
