async function editBackEnd() {
        const entryRef = doc(db, "accounts", user.uid)
        
        await updateDoc(entryRef, {
                "entry.0.payment": "League"
         })
     }

I'm trying to update certain fields in an array in firestore. I know there is no direct way to do so but with this code i am able to access the field but it removes all the other entries/fields.

How do I make sure it only updates the field that i want. in this cause im just trying to update payment of index 0

Im having issues uploading pics to stackoverlow so here's a couple url
