Bulk delete users added through SSO who will not be allowed product access

We have several hundred users in Aha! who have been added because they saw the Aha! icon on our SSO portal and were curious to know more. This has built up over the recent weeks and requires a lot of effort to delete each user individually when there are so many. We can bulk edit and add products, being able to delete in bulk with appropriate messaging and control (e.g. only a billing administrator can do the bulk delete) would save work.
