The definition of a Galois category was cooked up intentionally to create the general setting where Galois correspondences appear. There are plenty of the resources (e.g. here and here) that go into detail about Galois categories, their properties, etc.

However, I have not been able to find a source that explicitly states and proves the Galois correspondence in this general setting. Is there a resource that does this?

Anna Cadoret's article Galois Categories in Arithmetic and Geometry around Galois Theory.
