SF Symbols used in my app - do they embed in my app?

I am making a menu bar application for macOS that specifies SF Symbols as an Image. The application is now at a point where it has the functionality it needs. The question here is, are the SF Symbols used embedded in the application or something?

If I had to install SF Symbols in order to use the application I made, I would be in trouble.

I have 3 versions of macOS installed on my Mac. Only one OS has SF Symbols. When I switched the OS and tried it, the application icon was displayed even on the OS without SF Symbols installed, so I think it might be embedded, but I'm not sure. I would like to ask if there is anything left to do in the code. thank you.
