Investigation.

x-ms-original-file: 2024-03-01-preview/MongoClusters_ListConnectionStrings.json

automation read tsp-location.yaml to find out that directory: specification/mongocluster/DocumentDB.MongoCluster.Management

combine them (involve glob) to specification/mongocluster/DocumentDB.MongoCluster.Management/examples/2024-03-01-preview/MongoClusters_ListConnectionStrings.json

finally it would find it from example in Swagger e.g. specification/mongocluster/resource-manager/Microsoft.DocumentDB/preview/2024-03-01-preview/MongoClusters_ListConnectionStrings.json
