Oh, does it work for now?

If not I think the probably reason is you fetch kind 7 directly with wss://nfrelay.app/?user=activitypub ? Right?

["REQ","subid",{"kinds":[7]}] 

Currently filter logic in nfrelay.app only process REQ with kind 1. So you can't directly use kind 7 with any filter for now. Other kind beside kind 1 is not filtered 😅

You can probably use those kind 7 but need to check again from "e" tag in those kind 7 to nfrelay.app . Did certain kind 1 exist with those "e" tag

["REQ","subid",{"kinds":[1], "ids":["eventId1", "eventId2"]}] 

into wss://nfrelay.app/?user=activitypub

Not at the moment. I think will add into backlog feature later. Currently want to finish the main features at first.
