Can I use nested properties as variables while using useQuery from Apollo and GraphQL?

I created a MERN application using Graphql, and I’m trying to fetch using properties that are nested inside my data as variables. As an example, I have client and project models. Is it possible to fetch all the projects for a specific client by passing the client ID when fetching the projects with useQuery. Code examples are included. I removed import statements for succinctness. Also, I have the client.id (named clientId) available as a param in the url.

COMPONENT THAT CALLS USEQUERY

export const ClientProjects = () => {
  const { clientId } = useParams();

// variable set up is incorrect but gives an idea of what I'm trying to do
  const { loading, error, data } = useQuery(GET_PROJECTS, {
    variables: { id: { client: { id: clientId } } },
  });

  if (loading) return <p>Loading...</p;
  if (error) return <p>There was an error...</p>;

  return (
    <>
      {data.projects.map((project) => (
        <ProjectCard key={project.id} project={project} />
      ))}
    </>
  );
};

CLIENT EXAMPLE

id: 64f6081cf3af0aa2cfb57d62
firstName: "Bob"
lastName: "Barker"

PROJECT EXAMPLE

id: "64f677e0590bfbf82793407e",
title: "Company Website",
client: {
   id: "64f6081cf3af0aa2cfb57d62",
   firstName: "Bob", 
   lastName: "Barker"
}

PROJECT SCHEMA

// Project Type
const ProjectType = new GraphQLObjectType({
  name: "Project",
  fields: () => ({
    id: { type: GraphQLID },
    title: { type: GraphQLString },
    client: {
      type: ClientType,
      resolve(parent, args) {
        return Client.findById(parent.clientId);
      },
    },
  }),
});

PROJECT QUERY

import { gql } from "@apollo/client";

const GET_PROJECTS = gql`
  query getProjects {
    projects {
      id
      title
      client {
        id
        firstName
        lastName
      }
    }
  }
