Opening jnlp in fedora

I’m having trouble opening either the client or the designer jnlp. I’ve installed openjdk 11.0.13 and IcedTea, but I’m getting the following error. I’m using fedora 35 as my OS by the way. Could someone point me in the right direction to troubleshoot this?

JNLP doesn’t exist in newer versions of java. Use the native client launcher.

For older versions of Ignition where a JNLP is even offered, install java 8 with the native launcher or use the launcher’s bundled java (if offered).

I’ve worked through it, thanks.
