I need some help with the performance of a filter I made. It's taking 1.3s on updating a list of items. How could I improve this code to? I really have no idea.

useEffect(() => {
    const newAccounts = Object.values(accountGroups).map((ownershipType) =>
      ownershipType.map((group) => ({
        ...group,
        accounts: group.accounts.map((account) => {
          const isChecked = !!selectedFavoriteFilter.value;

          return { ...account, expanded: [{ selected: isChecked && account.isFavorite }] };
        }),
      })),
    );
    const filteredFavoriteAccountGroups = {
      single: newAccounts[0],
      shared: newAccounts[1],
      tutor: newAccounts[2],
      proxy: newAccounts[3],
    };

    setAccountGroups(filteredFavoriteAccountGroups);
  }, [selectedFavoriteFilter]);

useEffect(() => {
    const newAccounts = Object.values(accountGroups).map((ownershipType) =>
      ownershipType.map((group) => ({
        ...group,
        accounts: group.accounts.map((account) => {
          const isChecked = !!selectedFavoriteFilter.value;

          return { ...account, expanded: [{ selected: isChecked && account.isFavorite }] };
        }),
      })),
    );
    const filteredFavoriteAccountGroups = {
      single: newAccounts[0],
      shared: newAccounts[1],
      tutor: newAccounts[2],
      proxy: newAccounts[3],
    };

    setAccountGroups(filteredFavoriteAccountGroups);
  }, [selectedFavoriteFilter]);

I'm doing 3 loops to get to a deeply nested prop I have to add to each object in the list...
