Composite data entity not visible in Power BI


I have created composite data entity in Dynamics 365. I can see entity in Data Management but not in SQL DB or AX url. Where it is getting stored in SQL database(AxDB or AxDW)?

Data Entity url >>https://usnconeboxax1aos.cloud.onebox.dynamics.com/data/data entity name

I need to call composite Data Entity in Power BI and I cannot find in SQL.

If anybody have an idea then let me know.
