I think if it would be nice if we can direct users to which network/application they should switch to

While we can know the application the user initiated the transaction with, without changing the current WalletConnect setup, we have no means of knowing the network. Some applications also have the same name in different networks, only differentiator is chainID. So in such cases, if we tried to display the application to be switched to, the user would see an error message like Please switch application to lisk_mainchain and that would be confusing if they're on lisk_mainchain but on a different network
