How to return Hot Spare to Spare status

[EnigmaNas]

I have a Raidz2 pool with 7 drives and 1 hot spare. The pool reported a degraded drive, and the hot spare joined the pool as active. I replaced the degraded drive successfully, but the Spare did not return to spare status, and remains listed in the main pool along with the replaced drive.
How to I get the spare drive to return to spare status?
Here is the output from my zpool status -v statement -

Also, I would actually like to use the spare as the active drive and use the replacement as the hot spare. Is this possible?
Thank you for any assistance!

You either need to detach the original and leave the spare or detach the spare and it will go back to being a spare... see here https://illumos.org/books/zfs-admin/zfs-admin-ebook.pdf

Page as numbered on the "paper" 53-54 for the 3 possible options and what to expect.
