Module development and code questions

I have created a view (API endpoint) to fetch logs via an API. Now, I want to configure a rate limit for this API.

For this, I followed the Drupal documentation: https://www.drupal.org/project/rate_limits and downloaded the rate_limits module (https://www.drupal.org/project/rate_limits/releases/2.0.2).

Tagged routes - This module is for Drupal 8/9.
Is there anything like this module for Drupal 11 or how can we add tags to api routes in Drupal 11?

ERROR
preg_match(): Passing null to parameter #2 ($subject) of type string is deprecated StreamWrapperManager.php:294

CONTEXT

What module is this a bug in? I hope this is the correct forum to ask this.

This system looks broken

Android, Google Pixel 7a 

Also not clear how the elf to upload an issue screenshot. LoL 

And this isn't even the issue I'm here to check on or create. 😉🙄🤐

Is it possible to capture IDs of clicked-on inputs using logic from a behaviors file when the inputs are used in AJAX?

At a high level, I'd like to capture the IDs of elements when they're clicked-on. It looks like I can do it individually when using a mousedown handler with the respective IDs, but I want it to be more abstract in the sense of having a dynamic way of not needing to reference the ID in the code if possible.
