Grafana 9 tracing from elastic

We have tracing data/records in Elasticsearch. The schema is custom. But it has all the fields that map to open telemetry. The data was generated with open telemetry/tracing, just the field names and schema is custom.

Can this be shown using Grafana 9 tracing? What are my options short of rewriting my schema and telemetry collected so far?
Any pointers on how to get this working?
