Popover Container - Set Open by Default?

Hi everyone,

I absolutely love the popover container because it allows me to create a menu with various parameters that stays fixed at the top of the page as I scroll.

Since my main parameters are inside the popover, I would like to set it to be open by default when the page loads. Does anyone know if this is currently possible or if this feature might be implemented in the future?
Or do you know any Streamlit Component that implements that?

Thanks in advance!
Cheers,
Luca
