@dunlix yeah you should!
what does discord have to do with it? I tried using that link with different values and URL of course on my site, still didn't work. I'm sure it works for you, what am I missing?
To be honest: Nothing.
I am building a plugin for Discord integration..So the variable names are just placeholders if you want so.
The important part is at the end of my main post.
I hope that you find a slick way to use it for your community maybe.
