trying to create an opentelemetry trace using airflow - airflow

Question

I have been trying to create a trace using open-telemetry but the endpoint doesn't give out any results..
endpoint="http://localhost:55680"
any help appreciated
also did anyone try to install this package in airflow
! from opentelemetry.exporter.cloud_trace
(this package helps to create a trace in google cloud , trying to run that through airflow)
it throws a version error
