They're pretty easy to do/take IME, but you may find that it could be getting too cool for success now, but certainly worth trying.
Try & get a non flowering shoot...if not poss snip off the flower. Cut cleanly beneath a node, dip into hormone rooting powder/liquid, shake off the excess & push cutting around the edge of a pot filled with say cutting/seed compost, but any MP should be fine too.
Take several more cuttings & I'd also use a plastic bag over the whole using an elastic band to secure. Oh & label pot too.
Water pot & put the whole into a coldframe, if you've got one, or say beneath a piece of glass leaning against a part shade wall & forget about it!
Come next Spring I'd investigate- remove the covering bag. You'll now need to watch re water needs...As the weather warms up any new growth should be obvious.
If it's failed, try again early summer when success should be easier. Good luck, J.
