/**
 * Connect to NEAR using the provided configuration.
 *
 * {@link ConnectConfig#networkId} and {@link ConnectConfig#nodeUrl} are required.
 *
 * To sign transactions you can also pass:
 * 1. {@link ConnectConfig#keyStore}
 * 2. {@link ConnectConfig#keyPath}
 * 3. {@link ConnectConfig#deps.keyStore} (deprecated, only for use in legacy applications)
 *
 * If all three are passed they are prioritize in that order.
 *
 * @see {@link ConnectConfig}
 * @example
 * ```js
 * async function initNear() {
 *   const near = await connect({
 *      networkId: 'testnet',
 *      nodeUrl: 'https://rpc.testnet.near.org'
 *   })
 * }
 * ```
 * @example disable library logs
 * ```js

 *      networkId: 'testnet',
 *      nodeUrl: 'https://rpc.testnet.near.org',
