Close this request for waiting too long.
I updated the plugin myself.

@ErythroCraft would you mind sharing your work? I also contacted you on facebook regarding the same thing.
You can also get in touch via discord if you're willing to share. Saajid#0001

@SaajidDE
Sorry, but this is not allowed. I created by self. (It's an simple compile with JDK 16)
I can not do the work of @JamesPeters98 and I'll delete my forke after update.
