Execution permissions (chmod + x)

I have a Streamlit app named chess-app that uses the Stockfish chess engine. I’ve uploaded the Linux executable (stockfish-ubuntu-x86-64-avx2) to the root of my GitHub repository.

However, the app shows an AttributeError which indicates that the executable cannot be started. This is an indication that the file lacks execution permissions on your server.

Please, could you grant execution permissions (chmod +x) to the file stockfish-ubuntu-x86-64-avx2 on my app’s server?

Thank you for your help.
