missing pandas requirement

I have a fresh conda environment with python 3.9 on windows. I've used poetry to install solara.

When running the quickstart example:

import solara

@solara.component
def Page():
    clicks, set_clicks = solara.use_state(0)
    def increase_clicks():
        set_clicks(clicks+1)
    solara.Button(label=f"Clicked {clicks} times", on_click=increase_clicks)

I get the error:

Traceback (most recent call last):
  File "C:\Users\jhsmi\Miniconda3\envs\py39_solara\lib\site-packages\reacton\core.py", line 1457, in _render

    types = [import_item(t) if isinstance(t, str) else t for t in types]

    module = __import__(".".join(parts[:-1]), fromlist=[parts[-1]])
ModuleNotFoundError: No module named 'pandas'

While I would expect pandas to be either optional (for this example) or listed as requirement

widgetti / solara
