Return value customization

[topninja]

I am gonna get suggest data excluded метро - {street_type: "м"}
I tried to do by adding params on locations prop but no luck yet.
so I think when get data from api, I could throw data by filter "street_type".
How to resolve this?
I tried like this but have no idea how to do on this vue component.
