RFE: Cannot write NFC-V tag

[marcmerlin]

Describe the enhancement you're suggesting.

Describe the bug.

I'm using the latest available firmware as of today. I have an NFC-V tag on a water filter that I'd like to duplicate to a blank tag, but copying is not offered for this type of tag, only emulation and that emulation didn't seem to work (my water filter didn't see the emulated tag at all, or didn't like it).

Old versions of flipper zero recognized the tag as ISO15693-3 (unknown)

New (today's) firmware, recognizes the tag as SLIX

For comparison, the same tag seen by android

Reproduction

Reading the tag works, emulating it seems to work, but at least in my case does not. I can't tell if the emulation is bad or if I have another issue.
But more importantly, there is no 'copy' option that I can find.

I bought these 2 kinds of tags, but currently cannot write to them:

Any idea what I'm doing wrong, or not supported yet?

I may have filed this in the wrong repo originally, namely DarkFlippers/unleashed-firmware#836
apologies for that.
I'm happy to close the other one if appropriate
