How can I determine if the third party software "Razer MacOS" is safe to load onto my MacBook Pro?

I've purchased a particular gaming mouse (a Razer Viper Ultimate) to use with my video editing work, but unfortunately the developer doesn't support Mac anymore (they don't have software that connects their mouse to osx 13.5.2; they stopped developing their Mac driver at osx 10.15).

I've found a third party piece of software called "Razer macOS" which is supplied via Git Hub; however when I try to load this software, I get the apple warning that the software hasn't been developed by an apple approved software developer, and of course it might contain malware.

Is there anyway to determine if this software is safe to use? (the mouse is useless without an apple driver)

Install and uninstall apps from the internet or a disc on Mac

Not from GitHub. You take your chances. I would suppose the Git Hub "community" would likely have some way to flag the developer/software if it did contain malicious code. So, it is probably ok.
