Trace applications does not work as expected when Vertx Rx Java used. (dynatrace, datadog, open telemetry etc)

Hello, we are preparing to migrate our entire backend vert.x based custom framework as a payment company based on Turkey.
However we have a major issue regarding to integrate trace applications such as dynatrace, datadog or equivalent. Messages goes through event bus seems untracable and since our operations are mission critic, we required to integrate a tracing applications to our systems. Our team on hard schedule migrating our entire legacy backend as well as maintaining legacy backend so we are unable to contribute development process for this feature.
