Does anyone have the code to do a lightning channel probing?

[BrutalBear]

Hi guys, I am working on a project that requires me to figure out the lightning channel balance. I am wondering if anyone here has the code of a prober?

I'm not sure it's still possible to do, I thought an update a few months ago after it was revealed was made to ensure a balance of channels couldn't be determined (not sure if it's the same for old software or not considering how routing works).
