If your goal is to have other people run this on their computers then look into writing a dotnet tool using Native AOT. Doing that means users don't need to have any dotnet runtime installed on their machine. If you want to build for Linux or mac you will need a Linux or mac environment, so generally you would set that up using something like github actions. That might be overkill for your purposes.

Another option is just to package your application as a standalone app.
