How to register the Token's metadata

[droslean]

The only reference I found is

solana-go/cmd/slnc/cmd/token_registry_register.go

Line 117 in a5e17d6

registerTokenInstruction := tokenregistry.NewRegisterTokenInstruction(logo, name, symbol, website, tokenMetaAccount.PublicKey(), registrarPubKey, tokenAddress)

Is there any other documentation that I can follow?

Trying to add the metadata to an existing token account results in an error

2024/06/06 04:16:40 failed to send transaction: (*jsonrpc.RPCError)(0xc00036c420)({
 Code: (int) -32602,
 Message: (string) (len=78) "invalid transaction: Transaction failed to sanitize accounts offsets correctly",
 Data: (interface {}) <nil>
})
exit status 1
