How to use it

In this example, we are going to return all supported networks for the wallet connector. 
import { useDynamicContext } from '@dynamic-labs/sdk-react-core';
import { isWalletConnectConnector } from '@dynamic-labs/wallet-connector-core';

const MyComponent = () => {
  const { primaryWallet } = useDynamicContext();

  const getWCSupportedNetworks = async () => {
    if (!isWalletConnectConnector(primaryWallet?.connector)) {
      return;
    }

    const supportedNetworks = await primaryWallet.connector.getSupportedNetworks();

    console.log('supportedNetworks', supportedNetworks);

    return supportedNetworks;
  };

  ...
};
