Qt for Python (PySide/Shiboken)

Hope for some guidance. qt.shiboken: (bindings) /home/skinkie/Sources/reproduced/maplibre-native-qt/vendor/maplibre-native/include/mbgl/renderer/query.hpp:16: Stripping argument #1 of void mbgl::RenderedQueryOptions::RenderedQueryOptions(std::optional<std::vector<std::string> >,std::optional<mbgl::style::Filter>) due to unmatched type "std::optional<std::vector<std::string> >" with default expression "std::nullopt": Unable to translate type "std::optional<std::vector<std::string> >": Cannot find type entry for "std::optional". Documention mentions: https://doc.qt.io/qtforpython-6/shiboken6/typesystem_specifying_types.html#typedef-type Now that would be analogue to? <namespace-type name="std"> <value-type name="optional" generate="no"/> </namespace-type> <typedef-type name="StringVectorOptional" source="std::optional&lt;std::vector&lt;std::string&gt;&gt;"/> Now that does not seem to be the case: qt.shiboken: (bindings) template baseclass 'std::optional<std::vector<std::string>>' of 'StringVectorOptional' is not known Any suggestions?
