Pushdataset - Get table API is not returning column schema and other properties.

As per the below API it should return the table names as well as column schema and other properties like description, measures etc
https://learn.microsoft.com/en-us/rest/api/power-bi/push-datasets/datasets-get-tables-in-group#table
But we have observed that it just returns the table name.

Please check the attached screen for reference:
