Adding a malware exclusion to a file or folder, how to?

Good morning everyone, I am running into a small problem with a file on my new Mac that I need some help with.
For context, I installed Stardew Vally and the needed accessibility files, to run the game with said mods though I need the stardew mod file, which comes with the game and is a unix file opened in Terminal. Normal running of the game works fine, but as soon as I run the modding appi, mac OS instantly declares it malware and puts it into the recycle bin, it doesn't even ask if I want to open the file anyway as it does with other files.
I tryed getting around this by disabling gatekeeper and allowing apps from anywhere, this didn't do the trick though.
Any ideas where I can tell Mac OS that the file is no risk?

Thanks in advance.

Greetings Moritz.
