Question Tracking a physical pen in augmented reality.

Hello, I am currently trying to figure out the best way to track a pen in augmented reality. I am currently using vuforia for a different part of my application so I have tried to use that to track the pen by playing am image target at a certain point of the pen and then having an image representation that gets the position of the tip of the pen. While this works, it is very glitchy as the image target is not always being tracked. I was wondering if there was any other way people have attempted to do this. I have been sugested to place other types of markers onto the pen like a colored piece of tape etc. These suggestions however all seem to require another plugin that requires camera access. In the past I have attempted to use vuforia and mediapipe together but I have only come across camera feed conflicts that make this not possible. Any ideas?
