Backtracing Async functions (+Task return type)

[HomerSimpson00007]

Was using the Backtracer (Works very well!), But entountered a problem, when trying to trace an async function, the backtrace result is always the same, all functions originate from MoveNext function (Due to the Statemachine), example:

  Il2Cpp.backtrace(Backtracer.ACCURATE)
      .methods(CryptoUtils.method("WriteBinaryAsync"))
      .and()
      .attach();

0x06301eb8+0x000 TBetterBinaryProtocol::WriteBinaryAsync
0x062ccf98+0x094 Thrift.Protocol.TProtocol.<WriteStringAsync>d__39::MoveNext

Any other idea to backtrace such functions?
