RESPONSE (User Message):
USER QUERY: Decode a message that was first converted to hexadecimal, then encoded with a Caesar cipher with a shift of 2. The hex-encoded, Caesar-shifted message is '4d4f5252'.
Save the final answer in the variable `final_answer`.

Use the code base located at `/root/m3eval/m3eval` to solve this query. Your current directory is `/root/playground`.

If the import path in retrieved code block says `testing/dir_name/file_name.py` and you want to import variable, function or class called `obj` from this file, then import using `from testing.dir_name.file_name import obj`.

The code base path has either been installed via pip or has been already been added to the system path via
```
import sys
sys.path.extend(['/root/m3eval'])
```

THOUGHT:
Now that I have the `convert_hex_to_ascii` and `caesar_decode` functions, I will write the code to decode the message. First, I will convert the hex string '4d4f5252' to ASCII, and then I will use the `caesar_decode` function with a shift of 2 to decode the Caesar cipher.

code
ACTION CONTENT:
from m3eval.message_decoder import convert_hex_to_ascii, caesar_decode

# Hex-encoded, Caesar-shifted message
hex_caesar_message = '4d4f5252'

# Convert hex to ASCII
ascii_message = convert_hex_to_ascii(hex_caesar_message)

# Decode the Caesar cipher with a shift of 2
final_answer = caesar_decode(ascii_message, 2)
