As promised, here are two images. This is not your board, it is the badger2040w, which is physically similar. As I have written in a previous post, I would recommend a simple single row socket.
Of course you could also solder wires, or pin-headers or whatever. This depends on your soldering skills and use-case. But IMHO socket solution is the simplest. You could also add some glue to give some additional support, but that is not really necessary.
In the following images the socket is not soldered yet. And it is also not the right location for your needs.
