Do I have to use user-defined options in the kea config file?

Never mind I solved my issue.I needed to build the option and suboptions like
this in my unit test:
// add options 82 (both suboptions) to the request.
OptionDefinitionPtr rai_def =
LibDHCP::getOptionDef(Option::V4, DHO_DHCP_AGENT_OPTIONS);
ASSERT_TRUE(rai_def);
OptionCustomPtr rai(new OptionCustom(*rai_def, Option::V4));
const uint8_t circuit_id_data[] = {
0x01, 0x11, // Agent Circuit ID (length = 17)
// "Ethernet10:2026"
0x00, 0x0f, 0x45, 0x74, 0x68, 0x65, 0x72, 0x6e, 0x65, 0x74, 0x31, 0x30,
0x3a, 0x32, 0x30, 0x32, 0x36
};
OptionPtr circuit_id(new Option(
Option::V4,
RAI_OPTION_AGENT_CIRCUIT_ID,
OptionBuffer(
circuit_id_data, circuit_id_data + sizeof(circuit_id_data))));
rai->addOption(circuit_id);
const uint8_t agent_remote_id_data[] = {
0x02, 0x13, // Agent Remote ID (length = 19)
// "00:1c:73:8c:d0:e5"
0x00, 0x11, 0x30, 0x30, 0x3a, 0x31, 0x63, 0x3a, 0x37, 0x33, 0x3a, 0x38,
0x63, 0x3a, 0x64, 0x30, 0x3a, 0x65, 0x35
};
OptionPtr agent_remote_id(new Option(
Option::V4,
RAI_OPTION_REMOTE_ID,
OptionBuffer(
agent_remote_id_data,
agent_remote_id_data + sizeof(agent_remote_id_data))));
// OptionBuffer agent_info_buf = createAgentInformationOption();
rai->addOption(agent_remote_id);
// auto agent_info = boost::make_shared<Option>(
// Option::V4, DHO_DHCP_AGENT_OPTIONS, agent_info_buf);
query->addOption(rai);
handle_->setArgument("query4", query);
Then on the server side:
OptionDefinitionPtr rai_def =
LibDHCP::getOptionDef(Option::V4, DHO_DHCP_AGENT_OPTIONS);
OptionCustomPtr rai = boost::dynamic_pointer_cast<OptionCustom>(
query4_ptr->getOption(DHO_DHCP_AGENT_OPTIONS));
OptionPtr circuit_id_opt = rai->getOption(RAI_OPTION_AGENT_CIRCUIT_ID);
