Ok, lots of pics, hopefully this will make sense
from nostrudel-
hit the little "..." in the bottom corner the hit "<>View Raw"

Then copy the NIP-19 Encode Id (note1....)

And paste it into the field on nostr-delete

And click on Advanced: Nostr Relay Selection and then Load My Kind 10002 Relays

Then click Sign and Publish Deletion and you should get all the relays it successfully deleted it from.

Deletes request can take a while, and some relays won't delete things, but it mostly works.
