Cannot send SC MacOs standalone to another computer

Hi there,
I recently used this standalone repo (GitHub - dathinaios/sc_osx_standalone: A minimal SuperCollider standalone template for macOS.) to pack an app I made with SuperCollider. Unfortunately when I send it via WeTransfer to a friend of mine it would simply say “Cannot open application” without any additional information. However, if I do chmod +x to the executable file under /App/Contents/MacOS/App then it will open, but it would say “sclang: Permission denied”.
I’m quite at loss here, does anybody have more insights on this?
