Hi, I can't make ox-latex use a different class for a subtree using EXPORT_LATEX_CLASS, as stated in the docs: https://orgmode.org/manual/LaTeX-header-and-sectioning.html I am trying to change a specific subtree to a different layout (using tcolorbox) than the one provided in the main document class (sections) Thanks for your help!!
