Why isn't spark working for me?

So I do know the problem is that I changed the version of the server (papermc) to 26.2 but is spark not supported with the new version? I tried downloading the latest ver from the actual website and dropped it in the plugins, restarted the server and checked if it was working but to no luck. Please, I need help on why it isn’t working, is it really because its 26.2?
