Searching for category with subcategories in javascript array of objects

I’m building a search functionality where I need to search for a specific value to be find by part of its text.
So I’ve got an example object:

const data = [
  {
    org_name: "A PFS COUNTRY TESTS",
    clients: [
      {
        name: "Abu Dhabi",
        type: "Yacht",
        currency: "EUR",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      },
      {
        name: "Australia",
        type: "Yacht",
        currency: "AUD",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      },
      {
        name: "Bermuda",
        type: "Yacht",
        currency: "EUR",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      }
    ]
  },
  {
    org_name: "Music Tours",
    clients: [
      {
        name: "Music Demo",
        type: "Office",
        currency: "GBP",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      },
      {
        name: "Summer Tour",
        type: "Office",
        currency: "GBP",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      },
      {
        name: "Winter Tour",
        type: "Yacht",
        currency: "USD",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      }
    ]
  },
  {
    org_name: "Dariusz Sandbox 1",
    clients: [
      {
        name: "Dariusz Test Client 1",
        type: "Yacht",
        currency: "EUR",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      },
      {
        name: "Dariusz Test Client 2",
        type: "House",
        currency: "GBP",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      },
      {
        name: "Dariusz Test Client 3",
        type: "Aircraft",
        currency: "USD",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      }
    ]
  },
  {
    org_name: "Dariusz Sandbox 2",
    clients: [
      {
        name: "Dariusz Test Client 1",
        type: "Yacht",
        currency: "EUR",
        notifications: {
          for_action: 0,
          for_attention: 0
        },
        unpaid_invoices: {
          total: 0,
          ok_to_pay: 0,
          reviewed: 0
        }
      }
    ]
  }
];

So if I’m looking for a “Dar” I should receive array with only org_name objects that have clients that include the “Dar” in their name value.

My solution is so far:

const newData = data.map((el) => {
  const filtered = el.clients.filter((client) => {
    if (client.name.includes("Dar")) {
      return client;
    }
  });
  if (filtered.length > 0) {
    return { org_name: el.org_name, clients: filtered };
  }
  
});

console.log("newData is", newData);

But what I’ve got is [undefined, undefined, Object, Object]
instead of [Object, Object]
