How do I find my JST in a world without AKO?

Since the shutdown of AKO, I find it hard/impossible to access or even locate some of the resources that were once just a couple mouse clicks away. The topic in particular that I’ve been trying to find all over again is my Joint Service Transcript (JST). No matter how many times I search for it I can never find a working link that will allow me to access and view it. Who knows the easiest and fail proof way to get into it either step-by-step or just by use of a link?
