Can't get any response from scans

Sorry if this is a stupid question but I have been trying for hours on end and the commands don't give any results for me. It displays the help text correctly but once I add anything to it (like --scan, --scan with file path, --scan-history etc.) it just runs and goes to next line in terminal without any indication of whether something happened or not. Even tried giving it a non existent file name and that didn't produce any error. Nothing at all. Did I make a mistake with hooks? I don't understand it but did "git secrets --install" in the vulnerable directory. Is this the correct way?
Please help me understand this. I am new to it.

Reproduce the reported --scan, --scan-history, and nonexistent-file commands after running "git secrets --install" in a test repository. Start by checking the command output and hook behavior described in the issue; done means the no-output behavior and expected error or scan result are clearly explained or reproduced.
