My phone with NFC died a year ago so… Take what I say with a pinch of salt.

If I remember correctly you can use NFC tools pro to emulate a NFC tag. It doesn’t always work. I think it’s in the write section then emulate.

There are however hardware limitations on emulation because of sector 0. Maybe try to copy your NFC card to a blank NFC tag (get it cheap on eBay) then if it succeeds go toward emulation.
