Does anyone know how to remove individual graphics objects?

I just need to know the command to reference and remove graphics either by key, index, timestamp, history, whatever. I’m making some indicators and this is a dead end. I’ve messaged a bunch of people and have gotten no response. I’ve searched high and low in the cryptic api/ git docs, scoured code of other indicators, and exhausted 3 separate AIs. Nothing. There really just needs to be one master example indicator that showcases every possible function, and a detailed companion readme.
