These web api endpoints will help you to understand the things & achieve what you want.

https://crmdev.crm.dynamics.com/api/data/v9.1/privileges?$select=name

For ex. When I pass my System User GUID to the first function - the second url result says I have Global (Organisation) level Create privilege.

{"Depth":"Global","PrivilegeId":"a8bff87f-0df0-41d4-babd-f093faf1e32c","BusinessUnitId":"b08c8c6c-5c20-e511-80f7-c4346bac59ac"}

{"@odata.etag":"W/\"101387508\"","name":"prvCreateContact","privilegeid":"a8bff87f-0df0-41d4-babd-f093faf1e32c"}
