Unable to view the version for the files & total number of items for a user's OneDrive's files lib

We have a user who left the company, and i want to move all his files inside his OneDrive site (private and shared) to a sharepoint document library.

Using the Office 365 admin (who can view the user's private files) >> i have selected all the user's OneDrive main folders >> click on "Copy To" >> select the destination sharepoint document library. and the process started.

but as part of verifying if everything will be copied correctly, i am not sure how i can view these info inside the user's OneDrive's Files lib:-

1. i am unable to view the total number of items inside the user's OneDrive's Files library. i tried to get this info inside the classic and modern UI but without any result. for example inside sharepoint site >> you can click on site content and get the total number of items inside any list/library. but how i can do this for the user's OneDrive site's Files library?

2. i am not sure if using the "Copy To" option (to copy files from OneDrive to sharepoint) will also copy all the files versions or not. to verify this i need to modify the user's onedrive's Files library view to show the version, so is this possible?

Thanks
