How to configure pandaproxy authentication

[devmentality0]

Hello!
I'm trying to secure redpanda in my project. We use kafka api and pandaproxy to access it. I've already setup sasl and tls for kafka api. Here is the config file:

pandaproxy:
  advertised_pandaproxy_api:
    - address: 127.0.0.1
      port: 8082
  pandaproxy_api:
    - address: 0.0.0.0
      port: 8082
redpanda:
  admin:
    - address: 0.0.0.0
      port: 9644
  advertised_kafka_api:
    - address: redpanda
      name: PLAINTEXT
      port: 29092
    - address: localhost
      name: OUTSIDE
      port: 9092
  auto_create_topics_enabled: true
  data_directory: /var/lib/redpanda/data
  developer_mode: true
  enable_idempotence: true
  enable_sasl: true
  enable_transactions: true
  kafka_api:
    - address: 0.0.0.0
      name: PLAINTEXT
      port: 29092
    - address: 0.0.0.0
      name: OUTSIDE
      port: 9092
  kafka_api_tls:
    - cert_file: /etc/conf/node.crt
      enabled: true
      key_file: /etc/conf/node.key
      name: OUTSIDE
      truststore_file: /etc/conf/ca.crt
  node_id: 0
  rpc_server:
    address: 0.0.0.0
    port: 33145
  seed_servers: []
  superusers:
    - admin
rpk:
  coredump_dir: /var/lib/redpanda/coredump
  enable_memory_locking: false
  enable_usage_stats: true
  overprovisioned: true
  tune_aio_events: false
  tune_ballast_file: false
  tune_clocksource: false
  tune_coredump: false
  tune_cpu: false
  tune_disk_irq: false
  tune_disk_nomerges: false
  tune_disk_scheduler: false
  tune_disk_write_cache: false
  tune_fstrim: false
  tune_network: false
  tune_swappiness: false
  tune_transparent_hugepages: false
schema_registry: {}

Accessing kafka api works well, but now I can't connect via pandaproxy. It seems, that I have to authenticate proxy reques somehow. But I haven't found how to do it in documentation. Could anyone help me with that, please?

Now I have such errors doing curl -s "localhost:8082/topics":

{"error_code":50302,"message":"{ node: -1 }, { error_code: broker_not_available [8] }"}

And logs:

INFO  2022-05-31 05:11:28,377 [shard 0] kafka - connection_context.cc:308 - Detected error processing request: std::runtime_error (Unexpected request during authentication: 3)

Okay, I've found pandaproxy_client section in cofigs. Probably, that's what I need
