How to add item to collection which is a property of a parent collection?

[Anonymous]

I am trying to add more items to Location property but unable to via Patch or Collect

ClearCollect(
    incomingPeople,
    {
        Id: 10,
        Locations: [{Geography: "UK"}]
    }
);

Clear(selectedPeople);

ForAll(
    incomingPeople,
    Collect(
        selectedPeople,
        {
            Id: Id,
            Locations: ForAll(
                Locations,
                {Geography: Value.Geography}
            )
        }
    )
)

Attempt 1 - fail

Collect(LookUp(selectedPeople,Id=10).Locations, {Geography: "France"})

Attempt 2 - fail

Patch(LookUp(selectedPeople,Id=10).Locations, 
// not sure what to put as 2nd param,
{Geography: "France"})

Another attempt - fail

Patch(selectedPeople
, LookUp(selectedPeople,Id=10),
{Locations2:ForAll([{Geography:"France"}], {Geography:Value.Geography})})

Hi @Anonymous thanks for posting in the PowerApps community. Are you still having trouble with adding an item and can you review the above reply and advise if it was helpful? 

Thank you,

Got it to work 

Patch(items, LookUp(items, Id=ThisItem.Id), {Locations:ForAll(currentLocations, {Geography:Geography, Division : Division, Country:Country, City:City, ProvinceState : ProvinceState})})
