Cannot retrieve grading_period tables data using canvas data API

[yoonlees]

The same question was asked three years ago but I can't find a good answer. I can't retrieve  grading_period_fact, grading_period_score_fact, grading_period_dim,  grading_period_group_dim, grading_period_score_dim tables from Canvas using API call. Is this something to do with the account I use or these grading tables are protected and cannot be retrieved?
