Here is the code for AS5600 library, two sensors on one bus. Maybe you can add it in the examples.

FYI
Moved the issue to the right repo and added syntax highlighting.

I am working on a PR, so probably I can include it tomorrow.

added this header + some newlines to give credit to your sketch.

//    FILE: AS5600_plus_AS5600L.ino
//  AUTHOR: laptophead
// PURPOSE: showing working of a AS5600 and AS5600L side by side
//     URL: https://github.com/RobTillaart/AS5600

(update)
PR is running, to be continued tomorrow.
