How to debug latest changes

[sewbacca]

I am trying to implement a feature and want to debug the server. I found this article about debugging in the wiki, however when I attach to an instance, the breakpoints are misaligned. I guess it's because my instance does not have the bleeding edge version. What I did as a workarround:

1. Make a hard junction from the repo to .vscode\extensions\sumneko.lua-3.6.3-win32-x64\server
2. Anytime i change something, reload the testing instance.
   This has the drawback (or advantage) that it will affect any instance. Is there a proper way for testing? Like launching a test instance, which uses the server by default, but only during testing?

Regular practice:

1. Clone https://github.com/sumneko/vscode-lua
2. cd vscode-lua/client
3. npm install
4. Build or download binaries into vscode-lua/server/bin
5. Open vscode-lua in VSCode
6. Debugger launch Luanch Client

My practice:
Clone vscode-lua into <USER>\.vscode-insiders\extensions\

I'm a little confused. So when I am editing the server, I am not supposed to clone the language server itself, but the vscode extension?
And to make my current edited instance launch, I would need to compile it and copy the files into the cloned vscode-extension?
Couldn't I bypass all those compiling and copying shenanigans and tell the extension to launch a different executable as the server?
