Sharepoint PnP Modern search subsite filter

Hello,

I am implementing a PnP modern search, I am searching for files within one site and my query template in search result is {searchTerms} AND (Path:"https://testsite.sharepoint.com/sites/test1") withing test1 site I have 3 subsites. In search filter I want to show those 3 subsites as filter options so whenever I click on any subsite name in filter, search result will shows files only from that subsite.

By default it shows files from all site including test1 site and all 3 subsites.

Can anyone please help me on this?
