Creating WaaS wallet accounts once user already has WaaS wallet accounts
You can pass an array of chains to the createWaasWalletAccounts method to create wallet accounts for those chains.
If the same chain is passed multiple times, just as many wallet accounts will be created for that chain
If you didn’t add the required WaaS extensions for the chains that you are trying to create wallet accounts for, it will throw a NoWalletProviderFoundError.
