rxJava3 and Vertx injection in jUnit5 tests

[P R]

Using Vert.x 4.1.0 version:

I'm trying to inject io.vertx.rxjava3.core.Vertx using the @ExtendWith(VertxExtension.class) mechanism in jUnit5. However, I get the below error:

org.junit.jupiter.api.extension.ParameterResolutionException: No ParameterResolver registered for parameter [io.vertx.rxjava3.core.Vertx arg0]

Looking at the java docs, it doesn't seem to refer to this scenario i.e. the  io.vertx.rxjava3.core.Vertx as an injectable type. Hence is this a bug or is this use case not supported?

Thanks.
