This code performs a query on a database table called "WorkflowMenuEntity" to retrieve workflow-related data. It uses several left joins to include data from related tables such as "ResourceEntity", "WorkflowNodeEntity", "WorkflowNodeConfigEntity", and "WorkflowActionEntity". The selected columns are used to create a new instance of a custom type called "WorkflowResult" that contains information from all the joined tables.

The final result is a paged list of WorkflowResult objects based on the specified paging parameters
