How I can get specific attributes from a nested relation?

Hi all
I have two models with CommunityVisit and CommunityRegion names, the CommunityVisit fields are:

regionId,
visitorIp,
userId

And the CommunityRegion fields are:

countryId,
provinceId,
cityId

In the CommunityVisit I have a region relation with CommunityRegion and in the CommunityRegion I have three relations with country,province and city models; I have to get country, province and city of a region in the CommunityVisit.
I use this query for getting it, but I want just select country, province, and city of CommunityRegion, How do I do that?

await CommunityVisit
      .query()
      .last()
      .with('region.country')
      .with('region.province')
      .with('region.city')
      .last()

U mean, you don’t want the region but it’s related models?
