Update/rerun input command every n seconds

[fritzrehde]

I would like the input displayed in fzf to update every n seconds (similar to the reload(...) command but automatically run every n seconds). Is this possible somehow? Is there a linux tool to rerun the input command every n seconds that could then be piped into fzf?
Thank you!

You can periodically feed input lines to fzf,

while true; do
  date
  sleep 1
done | fzf

but you can't clear the previous list like reload does.

I'm not adding event types that are not directly triggered by the user (in this case we can imagine a "timer" event bound to reload action) as I believe that can be quite confusing to the users. (e.g. Input list suddenly disappears/changes in the midst of performing various actions; typing in a query, moving the cursor up and down, selecting multiple entries, etc.).
