3 years ago I am correcting my entry. You can still set this up by switching temporarily to "Visual Studio Team Foundation Server" just to set your custom tool.
And then follow the instructions as stated in the code

I was able to set Beyond Compare as my custom tool for this extension.
Installed product versions
Description
Current implementation is checking registry for a custom tool but this registry doesn't exist probably from version Visual Studio 2019. Probably this needs to re implemented using/checking for the tool in the global C:\Users\username.gitconfig or any other option?
Steps to recreate
Current behavior
Compare files is using default Visual Studio comparison tool and it seems there is no way to set the custom tool (unless manual entry to registry folder)
Expected behavior
The external/custom tool should open
