Where can I find the NBT tags for specific items, like "tacz:9mm" and so on? I've tried F3+H, but it only gives the generic NBT tag (e.g., "tacz:ammo" or "tacz:attachment") used for all the items of that category. I'd like to have easy access to these if possible.

you can just use vanilla command /data get entity @s Inventory to check detail nbt tag of the items in your Inventory.

You have no idea how long I was looking for how to get it, thank you!!!
