@sumukhswamy code looks much cleaner now. Added some minor comments, can you please add jest tests for this file?

[ps48]

Can you please change the filename to https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/DEVELOPER_GUIDE.md#filenames. We added this file in 2.11 hence it should adhere to the OSD plugin guidelines.

do we want to consider using enum here? something like

export enum AsyncQueryLoadingStatus {
  SUCCESS = 'SUCCESS',
  FAILED = 'FAILED',
  RUNNING = 'RUNNING',
  SCHEDULED = 'SCHEDULED',
  CANCELLED = 'CANCELLED'
}

export enum TreeItemType {
  COVERING_INDEX = 'covering_index',
  SKIPPING_INDEX = 'skipping_index',
  TABLE = 'table',
  DATABASE = 'database',
  MATERIALIZED_VIEW = 'materialized_view',
  LOAD_MATERIALIZED_VIEW = 'Load Materialized View', // Consider renaming this for consistency
  BADGE = 'badge'
}
