Displaying Span Kind, Input, and Output in UI for Manual Instrumentation

Hi I'm doing Manual instrumentation here. How can I display the span kind, input, and output in the UI ?

with tracer.start_as_current_span(name="completions",
                                  kind=SpanKind.INTERNAL) as span:

As above I have configured SpanKind.INTERNAL, but in the UI it displays "unknown".

span.set_attribute("base_prompt", base_prompt)
span.set_attribute("query", query)

As above I have set attributes. The atrributes and status is working fine. What I need is to display span kind, input, and output in UI.
