Any renewal of an (expired) rating now requires a course at a flying school before you can fly the proficiency check.
While there are recommendations, ultimately the course duration and content are at the discretion of the school, and once you are done they give you a certificate. If they feel no training is required, they can issue a certificate saying so, but typically that is reserved to just a few days over or if you are demonstrably current using a different licence.
If you are a bit rusty, they should just go fly a test profile check you out, and if all is fine they will give you a course completion certificate and off you go into the test. If not, it's training as required until they do.
