 * Composable that returns existing connections of a `<Handle />`.

 * @param params.type - handle type `source` or `target`
 * @param params.nodeId - node id - if not provided, the node id from the `useNodeId` (meaning, the context-based injection) is used
 * @param params.id - the handle id (this is required if the node has multiple handles of the same type)
 * @param params.onConnect - gets called when a connection is created
 * @param params.onDisconnect - gets called when a connection is removed
 *
 * @returns An array of connections
