If you newbie, I would recommend to wait some more time until psram support is fully integrated into esp-idf master branch. At the moment you must use different esp-idf branch, specific toolchain build etc. ...
If you manage to setup your build environment, you can configure it to use psram the same way you are using internal RAM, with maloc function.
