BTC, DOGE example

[AmjadKhan2k18]

Hello WalletConnect,

I see WalletConnect now support BTC, DOGE, Litecoin it was merged last week

I went through documentation and tried to implement it in Flutter using WalletConnectV2 package but it doesn't connect at all, Trustwallet doesn't show BTC in list of chains when try to connect it
https://walletconnect-docs-git-fork-towolabs-main-walletconnect1.vercel.app/advanced/multichain/rpc-reference/bitcoin-rpc

i tried with multiple chainIds BIP122, BIP32, BIP43 nothing work at all

here is my code for chain to connect, am I doing something wrong?

   'bip122': const RequiredNamespace(
            chains: [
              "bip122:000000000019d6689c085ae165831e93",
            ],
            methods: [],
            events: [],
          ),

if there is any example available in web, react native, Android or IOS Please share so we can implement it as soon as possible
