Hey @adnanrahic , after thinking for a while, I believe that we can add more languages to think about: Ruby, Kotlin, and Elixir.

As I have experience building APIs in Ruby I can do it on: https://github.com/kubeshop/tracetest/issues/2249

On Kotlin and Elixir, we can have further development later.

Nice. We can add more programming languages.
