PySide6 in Conda environment: uic automation

[reinago]

I have added one specific Conda environment as a kit, which works fine for running (also in debug mode), but for some reason the "Run PySide6 project tool" build step has no entries for "PySide project tool:" and "PySide uic tool:".
I can run pyside6-uic fine from the Conda environment, but running it automatically from Qt Creator would obviously be much nicer. Currently, clicking the build step does not seem to do anything at all.

Maybe I have no project tool in the environment and this is throwing the Creator off? What executable should I be looking for? Could I manually add the respective paths to the .pyproject.user?
