Hey @cv65kr 👋🏻

It would be nice to have tests for the new temporal interceptors. You may write a dummy plugin-interceptor as I wrote in many places in the rr-e2e-test (e.g: link) and do some processing in it and then check the output.

@rustatian code improvements are done. Will write some test soon.
