How to sort alphabetically?

[HarleyDavidson86]

I have a collection like this one:

[
   { address: "a" },
   { address: "b" },
   { address: "A" },
   { address: "B" },
   { address: "c" },
   { address: "D" },
]

My query looks like this:

paginatedData, err := mongopagination.New(collection).Context(ctx).
   Limit(limit).
   Page(page).
   Filter(paginationFilter).
   Decode(&addresses).
   Sort("address", 1).
   Find()

I'd expect the following order in the response: a, A, b, B, c, D
but in fact it is: A, B, D, a, b, c

How can I sort the elements in alphabetically order? Is there a way to set a "collation" or something else?
