When the user already has one trial Kafka Instance running, he should not be allowed to create another one. Test that there is a warning displayed properly.
You might have to deal with this part of the code https://gitlab.cee.redhat.com/insights-qe/iqe-managed-kafka-plugin/-/blob/master/iqe_managed_kafka/entities/kafka.py#L552-564
The IDs that were used by these parts are not present in the UI anymore. You might have to

• Ask UI team to add some unique IDs to the warning
• Do it ourselves somewhere in https://github.com/redhat-developer/app-services-ui-components
• Locate the element by the warning's text that is displayed
