create offer

[AsliddinBuriev]

Hi everyone!
I'm new to web3 world. I want to create offer using opensea-js package.
I'm using
ethers: "^5.7.2" && opensea-js: "^6.1.12"
Here is the code:
const provider = new ethers.providers.Web3Provider(window.ethereum);
const sdk = new OpenSeaSDK(
provider,
{
chain: Chain.Klaytn,
apiKey: 'api key',
},
(arg) => console.log(arg),
);
const offer = await sdk.createOffer({
asset: {
tokenId,
tokenAddress,
},
accountAddress: await this.connector.getAddress(),
startAmount: price,
// expirationTime: (Math.round(Date.now() / 1000) + duration).toString(),
});

  But I get 
  "Specified accountAddress is not available through wallet or provider" error. 
  Indeed, when I checked there is no address in provider on creating sdk instance. 
  I dont know how can I get "address" in provider object. I would appreciate any help.
