Integration creating tons of entities

[Kosygor]

Hello just have installed You integration with configuration

 binance_pool:
   domain: com
   native_currency: USD
   balances:
     - TLM
     - BUSD
   api_key: !secret binance_api_key
   api_secret: !secret binance_api_secret

And it just started crating tons of entities. Did not count them and wait to see how many there are. Most of them were *_exchange. Could it be because i did no specify exchanges:? Edit: realy I did not read documentation well.... Closing
