Answer 1

Purely theoretically, any URL protocol can be registered in the system ( in windows ).
Associate it with any application that will perform the actions you need (for example, run other programs)
So, telegram registers the protocol during installation tg://, Skype - skype://.
For example, you register a protocol execprogam://, associate it with your self-written program or script, and make links like this on a web page. execprogram://calc.exe
I hope you understand that you need to manually register the protocol on each target computer and install your utility on this computer, which will work on this protocol.
Therefore, if you need a solution for internal use, for yourself, this is the right option.
