Filter relationship by value in parent

I have a query where I'm trying to filter related objects by a value that will be found in the root of the query. example

const response = await prisma.myObject.findMany({
  where: {
    myKey: true
  },
  select: {
    someId: true, // I want to filter 'someRelatedModel' where someRelatedModel.someId == this
    someRelatedModel: {
      where: {
        someId: // Only give me 'someRelatedModels' wher this is the same as the someId above
      }
    }
  }

const response = await prisma.myObject.findMany({
  where: {
    myKey: true
  },
  select: {
    someId: true, // I want to filter 'someRelatedModel' where someRelatedModel.someId == this
    someRelatedModel: {
      where: {
        someId: // Only give me 'someRelatedModels' wher this is the same as the someId above
      }
    }
  }

try someId: someValue?

I don't have the list of someId at this point. I can query to get the list of all of those, then do another query to get the related models, but I was just hoping I could somehow filter that someRelatedModel in this query. I guess I could just write the raw SQL to do it if the SDK doesn't support it. I was hoping there would be a solution like:

...
someRelatedModel: {
  where: { someId: '$.someId' }
}
...

...
someRelatedModel: {
  where: { someId: '$.someId' }
}
...

I want to be able to do this through the SDK if possible.

SELECT t.someId, o.otherColumn
FROM MyTable t
INNER JOIN MyOtherTable o ON t.someId = o.someId
WHERE t.myKey = true;

SELECT t.someId, o.otherColumn
FROM MyTable t
INNER JOIN MyOtherTable o ON t.someId = o.someId
WHERE t.myKey = true;

My brain broke. I just added a relationship between the 2 and it fixed it
