The OpenTelemetry console output with tracing details is printed when the `verbose` argument is set to `True` in the `phoenix.otel.register()` function. To hide this output, ensure you do not set `verbose=True` (either omit the argument or set `verbose=False`) when calling `register()` in your code. By default, this output is not shown unless `verbose` is enabled[^1^][^2^].
Example:
```
from phoenix.otel import register
tracer_provider = register(verbose=False) # or simply omit the verbose argument
```
