Hi,
Last time we checked, it requires the same toolchain as v5.1, so you can simply install it into it via the ESP-IDF release selector.
We will eventually release another toolchain that includes it out-of-the-box, but since the current toolchain works just fine with one very straight-forward extra step, it’s not a very high priority.
Update: We have released an updated toolchain with ESP-DF 5.2 included. You can download it here: https://gnutoolchains.com/esp32/
