Nested models with pydantic 2.0 about streamlit-pydantic HOT 1 OPEN

Ok, so the issue wrt. nested models not working with pydatnic 2 is resolved by the "suggested fixes".

However, the "list" not working seems to be an orthogonal problem, not related to pydantic 2 (but maybe changes in streamlit, compared to earlier versions):

List-Editing is solved in streamlit-pydantic among others by adding a button: self._render_list_add_button(key, add_col, data_list) (ui_renderer.py:1000), but that tries to add a streamlit.button(...) to the interface. However, adding a regular button within a form is disallowed by (at least current) streamlit button.py:407-411 raising an exception (which is then silently caught and ignored).
