Hi Wajid,
Thanks for posting in the community.
We would love to help you with your query, however, since it is related to Microsoft Graph, and we have a specific channel Microsoft Q&A Community coping with questions about SharePoint Activity API schema, I recommend you post a new thread (click "Ask a question" and add the tags Microsoft Graph and SharePoint) there for expert help.
Sorry that our category may have limited resources on checking on your concern further.
Thanks for your understanding.
