How to use the indy-sdk.proverStoreCredential function in indy-sdk

exports.acceptCredential = async function(theirDid, encryptedMessage) {
    let myDid = await indy.pairwise.getMyDid(theirDid);
    let credential = await await indy.crypto.authDecrypt(myDid, encryptedMessage);

    let credentialRequestMetadata;
    let pendingCredentialRequests = indy.store.pendingCredentialRequests.getAll();
    for(let pendingCredReq of pendingCredentialRequests) {
        if(pendingCredReq.credRequestJson.cred_def_id === credential.cred_def_id) { // FIXME: Check for match
            credentialRequestMetadata = pendingCredReq.credRequestMetadataJson;
        }
    }

    let [, credentialDefinition] = await indy.issuer.getCredDef(await indy.pool.get(), await indy.did.getEndpointDid(), credential.cred_def_id);
    await sdk.proverStoreCredential(await indy.wallet.get(), null, credentialRequestMetadata, credential, credentialDefinition);
    let credentials = await indy.credentials.getAll();
    console.log(credentials);
};

credentialOffer.data = {};
      console.log(e);
    }
    let [, credentialDefinition] = await indy.issuer.getCredDef(pool, endpointDID, credentialOffer.cred_def_id);
    let masterSecretId = await indy.did.getEndpointDidAttribute('master_secret_id');
    let [credRequestJson, credRequestMetadataJson] = await sdk.proverCreateCredentialReq(wallet, endpointDID, credentialOffer, credentialDefinition, masterSecretId);
    let schema = await indy.issuer.getSchema(credentialOffer.schema_id);

    let credentialValues = {};
    for (let attr of schema.attrNames) {
      if (credentialOffer.data[attr]) {
        credentialValues[attr] = {raw: credentialOffer.data[attr], encoded: indy.credentials.encode(credentialOffer.data[attr])};
      }
    }
    let [credential] = await sdk.issuerCreateCredential(wallet, credentialOffer, credRequestJson, credentialValues);
    await sdk.proverStoreCredential(wallet, null, credRequestMetadataJson, credential, credentialDefinition);
  } catch (e) {
      console.log(e);
  }
}
