How do i get an Ethereum address in python starting from a v,r,s signature?

Question

I am trying to get the address that signed the transaction below in Moonbeam EVM (a Polkadot EVM compatible parachain). By loading the contract ABI i am able to get the call parameters by doing this:

from web3 import Web3
w3 = Web3(Web3.HTTPProvider(endpoint))
contract = w3.eth.contract(address=contract_address, abi=abi)
func_obj, func_params = contract.decode_function_input(input)

However, I haven't found a way to get the signing address from the v,r,s value. The signing address is 0xb01744745fbBebE6A0Da674F8f45fD1e14D5B488 and Subscan can decode it (not sure how), the extrinsic can be seen here https://moonbeam.subscan.io/extrinsic/333456-3

This is the content of the extrinsic:

        }

    ],

  }
}

So how do I get the address from the above data? I have tried in many ways without finding anything that brings to that result.

P.S. I am aware that in this specific case I can get that address from one of the events triggered by the call but I do not want to use that method instead I want to decode the address that signed the transaction
