Problem with FirewallEvents API

Does “firewall Events” api work?

For exaple if i try to filter by country = ES it returns US results.
https://api.cloudflare.com/client/v4/zones/zoneId/firewall/events?country=ES&action=block (replaced zoneId)

block does not seem to be a valid action according to the documentation

Sorry I tried like 50 filters and none worked, in some situations it seems to sort (In this example it is sorting by action or something similar because it is showing in first place challenge actions, but then it shows the rest of them and it seems to be doing nothing with the country)

I am trying to filter by country but result is always the same:

https://api.cloudflare.com/client/v4/zones/zoneid/firewall/events?country=UA
https://api.cloudflare.com/client/v4/zones/zoneid/firewall/events?limit=10
https://api.cloudflare.com/client/v4/zones/zoneid/firewall/events?action=challenge

And multiple other combinations…

I’m running into a similar issue with since and until. Was anyone able to figure out why these optional parameters don’t work?

while the UI shows block, the action used in the API is actually drop
