To check Function signature:
1. Go to https://abi.hashex.org/
2. Below the title `"Or enter your parameters manually"` you should choose `"your function"` function type
3. Then enter `finalizeUpgrade_v3` as a function name.
You should get: `6d395b7e`
As you can see, it matches with the function signature from evmscript parser.
