How to determine if the scroll bar has reached the bottom in the Select component?

[exqmjmz]

I have a feature that needs to be implemented, where new content is requested and inserted into the dropdown options when the scroll bar reaches the bottom. However, I found that using "on:scroll" on "Select.Content" does not work, as there is no "on" method available.
How should I implement this functionality? Or which corresponding API can I use to achieve this functionality?
