Querying webcam API only for live feeds

[bonagro]

I am trying to query a list of all webcams of a specific category (building for example) where the live video is enabled.

I am trying this:
https://api.windy.com/api/webcams/v2/list/category=building?show=webcams:property=live,player

However it is producing the same result as

https://api.windy.com/api/webcams/v2/list/category=building?show=webcams:player

How can I generate a query to only include webcams who's live webcam is enabled?
