Are you talking about the example sketch from the library I shared in my last reply?
If so, the problem is probably this line:
This causes the sketch to wait in a perpetual loop until the Serial Monitor is opened when the sketch is running on an Arduino board with native USB capabilities (e.g., Leonardo, Micro, MKR, Nano 33 IoT). The reason this can sometimes be useful is because without it you will not see any serial output that was printed between the time the sketch started and when you get the Serial Monitor open. In this particular case, it can be useful to see the "Setup..." to prove the sketch started and the "complete!" to tell you that the library code was initialized successfully.
But once you have the code working and want to apply it to something that won't need Serial Monitor running, that behavior of hanging at setup is no longer useful and can be removed (or just comment it out to make it easy to enable again for troubleshooting).
