It is possible to specify a queue size greater than 256

I do it like this

iox::popo::SubscriberOptions subscriberOptions;
subscriberOptions.queueCapacity = 5000U;
iox::runtime::PoshRuntime::initRuntime(name_app);
iox::popo::Listener listener;
iox::popo::UntypedSubscriber subscriber_ses({"SES", run_context, "Event"},subscriberOptions);

after

listener
    .attachEvent(subscriber_ses,
         iox::popo::SubscriberEvent::DATA_RECEIVED,
         iox::popo::createNotificationCallback(get_events_wrapper))
     .or_else([](auto) {
          ::fmt::print("Error\n");
});

I get this message
[Warning]: Requested queue capacity 5000 exceeds the maximum possible one for this subscriber, limiting from 5000 to 256

Sorry for the stupid question, but can I increase the queue?

I found it here https://iceoryx.io/latest/advanced/configuration-guide/

I tried to build it like this
cmake -Bbuild -Hiceoryx_meta -DBUILD_SHARED_LIBS=ON -DIOX_MAX_PUBLISHER_HISTORY=32768
but it didn't help

my publishers produce a lot of messages and I would like to get a little more than 256 at a time, can I do it somehow? I really need help :)

Start with iox::popo::SubscriberOptions::queueCapacity, the UntypedSubscriber setup, and the warning that limits capacity to 256. Compare the configuration guide with the attempted I/OX_MAX_PUBLISHER_HISTORY CMake option to identify the relevant limit. Done means documenting or implementing a supported way to request a larger subscriber queue, with validation of the resulting capacity.
