createrawtransaction – EasyBitcoin-PHP not working with Rawtransactions RPC

I’ve been using easybitcoin to access “Wallet RPC” defined here – https://developer.bitcoin.org/reference/rpc/index.html#rawtransactions-rpcs

However, it doesn’t seem to work with “Rawtransactions RPC” like createrawtransaction or getrawtransaction. This call returns nothing.

Any ideas on how to get PHP to work with Rawtransactions RPC?
