### How to put Sage in Env Path?

I have installed Sage in windows 10 but for some reasons it's not in path. Running sage in cmd outputs: `'sage' is not recognized as an internal or external `~~command,
~~command, operable program or batch file.

.

I can't find sage.exe either to manually put it in path. What can I do?
The reason I need to have the path to sage.exe is because I want to use sagetex and it needs sage to be in path.
Currently, I' only able to produce .sout from sage by running sage manually and loading in the file manually. The sage that I'm loading has this full path:

`"C:\Program Files\SageMath 8.1\runtime\bin\mintty.exe" -t 'SageMath 8.1 Console' -i sagemath.ico /bin/bash --login -c '/opt/sagemath-8.1/sage'`

So I am not able to find sage.exe anywhere to automate this process possibly with latexmkrc.
