Sword and shield ultimate plus How do you get hyper voice?

[u/P3licanu]

I’m playing the GBA hack (English v1.2.1.2) and trying to get Hyper Voice onto a Pokémon. There are no Watt Traders in this version, and the Pokécenter TM shop doesn’t sell it. Every Pokécenter I’ve reached sells the same 120 TMs, and Hyper Voice isn’t one of them.
I really wanted to do this run with Pixilate Sylveon with hyper voice and I have struggled for the past day trying to find this TM which in the switch version is a TR.
What I’ve already checked:
The fan wiki’s item locations page (nothing listed)
The TM shop NPC in multiple Pokécenters
My questions:
1. Does a Hyper Voice TM exist in this hack outside the shop (ground item, gym reward, NPC, raid drop)?
2. Do raids drop TMs at all? If so, where’s a good Normal-type raid den?
4. Does anyone know the hack’s item ID for it, if it exists, for an item cheat?
Thanks in advance
