Change location sources in the weather widget

I use the kweather app and it has a variety of locations, including mine. However, when I want to select my location in the kde weather widget, it does not appear there. Why not use location sources for the weather widget from kweather, since there are clearly more of them?

The weather widget is not related to the kweather app.

Yes, I understand, but for example, they can add a feature so that the user can enter their own weather api into the widget if it is impossible to get a free api for everyone. Because right now this widget is just useless to me.
