Was master Yoda a puppet or real person in the last star wars movie?

Master Yoda was a puppet in the latest Star Wars movie, "The Rise of Skywalker" (2019). He appeared in a few scenes, utilizing archived footage of Frank Oz performing the puppet. However, the movie featured digital enhancements to the puppet's appearance and movements to make him look more realistic.

So, while Yoda was physically a puppet, his appearance was heavily digitally enhanced, creating a more lifelike impression.
