 * The parameters object for the `initPapi` function.
 *
 * Warning: It's initialized with `gtest` types descriptor!
 * To match types of a custom chain, initialize the client with your descriptor instead of using `api` returned by this function.
 * Example:
 * ```ts
 * import { gdev } from 'g1-papi/descriptors'
 * const { client } = await initPapi({ chain: 'gdev' })
 * const api = client.getTypedApi(gdev)
 * ```
 *
 * @param options - optional, the parameters object.
 * @param options.chain - The chain to connect to.
 * @param options.endpoint - The endpoint to connect to.
 * @param options.onConnecting - A function that is called when the connection is being established.
 * @param options.onConnected - A function that is called when the connection is established.
 * @param options.onError - A function that is called when the connection fails.
 * @param options.onClose - A function that is called when the connection is closed.
