Resource ID Help

This might be a dumb question, but how do you find the ID of a resource in the asset manager? because I can’t for the life of me find it, and the documents doesn’t even make it clear where to find it for some strange reason. What am I missing here? I’m asking because I’m using an extension that requires me to know this information

Which extension are you using?

The “Load Custom Image Extension” I’m hoping to use it to get around some limitations of the engine slowing down when I have a ton of animations in a sprite As I mentioned in another post. And not have to juggle with a ton of different sprites which leads to similar issues with having to control all of them in the event code.
