Remarks
The name will be used for a new relationship type if the description is used for purposes of creation. Otherwise, it will be used to identify an existing relationship type if the description is used for the purposes of modify or delete.

Example
Delete Entity and Relationship Types with SchemaBuilder
await QueuedTask.Run(() =>
{
  using (var kg = GetKnowledgeGraph())
  {
    if (kg == null)
      return;

    var entity_name = "PhoneCall";
    var relate_name = "WhoCalledWho";

    var entityDesc = new KnowledgeGraphEntityTypeDescription(entity_name);
    var relateDesc = new KnowledgeGraphRelationshipTypeDescription(relate_name);

    //Run the schema builder
    try
    {
      SchemaBuilder sb = new(kg);
      sb.Delete(entityDesc);
      sb.Delete(relateDesc);
      //Use the KnowledgeGraph extension method 'ApplySchemaEdits(...)'
      //to refresh the Pro UI
      if (!kg.ApplySchemaEdits(sb))
      {
        var err_msg = string.Join(",", sb.ErrorMessages.ToArray());
        System.Diagnostics.Debug.WriteLine($"Entity/Relate Delete error: {err_msg}");
      }
    }
