Training an ITS classifier

Hi Colin,
Thanks a lot for your solution.
When I ran the command 'Evaluate the classifier', I got the following error:
Plugin error from rescript:
A plugin named 'longitudinal' could not be found.

First, I'd appreciate it if you could demonstrate how to resolve the error.
Next, should I run the command using the 'qiime2-shotgun-2023.9' or 'rescript' environment?
Third, if I intend to use your pre-trained ITS classifier, should I apply and follow the 'Training feature classifiers with q2-feature-classifier' tutorial?

Thanks ahead of time!
