A Microsoft file hosting and synchronization service.
Hi Nebu Thomas Mathew,
Thank you for doing further tests and sharing the result with us.
We understand your concern is that there are many activities being done in user's OneDrive for business, but when you try to get audit report of OneDrive for business, the report only shows Viewed pages activity.
When testing in 3 different Microsoft 365 tenants, we found we can reproduce the same situation. If we directly put a user's OneDrive for business URL in the File, folder, or site box, the result only shows Viewed pages activity.
We tried to specify the activity(for example, Download file) and OneDrive URL, set the time range, then search log. No data is available.
And we also tried to specify user's name and OneDrive URL, it only shows Viewed pages activity.
Given this, we do understand the issue has affected your work. Very sorry for the inconvenience caused.
We're afraid this issue may need to be investigated from back end. The best way to further troubleshoot it is to report it to the related team. We would love to help you further, sorry to say that due to limited resource, we cannot fix the issue directly.
In this situation, we sincerely recommend you try to create a support ticket from Microsoft 365 Admin Center>Support>New Service Request. The support team over there has higher permission than us to investigate the issue from background, they have more resource and correct escalation channel in handling this kind of issues. This would be a more efficient way in handling the case for you.

Thanks for your patience and understanding so far.
Sincerely,
