Plugin / Function Missing

I use a custom plugin, and recently had to recompile it to add support for M1 macs and notarization. In that process, I basically rewrote the plugin and moved from a very old SDK to the latest one from FileMaker.

The problem: something I did changed the plugin's ID or name, so that when I use the plugin in my existing databases, all plugin calls are now showing as <Function Missing>

I don't use this plugin in that many spots, but it would be nice if FileMaker had a global search - Is there an easy way to search my scripts for all the missing function calls? (I do have MBS plugins if that helps)

Please check your plugin code.
If you use same plugin ID and function IDs, it should be seen in FileMaker once the plugin is loaded.
