How to use the apollo-client/util/observables.multiplex function in apollo-client

request: {
            payload: { mutation, variables, context },
        },
    } = offlineRecord;
    const query = client.queryManager.transform(mutation).document;
    const operation = {
        query,
        variables,
        operationName: getOperationName(query) || void 0,
        context: client.queryManager.prepareContext({
            ...context,
            forceFetch: true,
        }),
    };
    const options: Options = {
        observable: multiplex(execute(link, operation)) as any,
    };
    return observableToPromise(options, (result) => result);
}
