How to set transaction name for current trace using the custom Java SDK?

Hi,

I followed these instructions to set the transaction name for the current trace using the custom Java SDK but I get a NoClassDefFoundError. I'm using the latest SolarWinds java agent (2.0.0) and declare the same version in my pom file as follows:

<dependency>
  <groupId>io.github.appoptics</groupId>
  <artifactId>solarwinds-otel-sdk</artifactId>
  <version>2.0.0</version>
</dependency>

Whenever I call SolarWindsAgent.setTransactionName(transactionName) in either a custom SpanProcessor or a java instrumentation advice class I get a NoClassDefFoundError. I even tried declaring the SolarWindsAgent class as a helper in the InstrumentationModule class as follows:

@Override
public boolean isHelperClass(String className) {
    return className.startsWith("com.solarwinds");
}

I'm wondering what I need to do to set the transaction name programmatically using SolarWinds custom Java SDK.
