Dear Garima,
I think that the field type related logs can be got from APIs.
As you need some calls about the tenant, site and field item type in the Microsoft 365 Activity API, sorry for that our category may have limited resources on that.
The API call needs to be deployed and registered in Microsoft Entra. If it is convenient, I suggest you post a new thread on our specific support channel Microsoft Entra ID - Microsoft Q&A so that they can provide some call examples for your reference.
Meanwhile, we'll keep the thread open and welcome other experienced community members to share suggestions and opinions.
Your understanding is greatly appreciated!
Sincerely
Cliff | Microsoft Community Moderator
