Can't find this mod. Help!

hey guys, I'm trying to put the mod RPGZ into my. I couldn't find it by searching, and aternos says it's already available when I try to suggest it. here's the link to the mod on curseforge https://www.curseforge.com/minecraft/mc-mods/rpgz

my first thought is that it might be because it's tagged as a fabric mod on curseforge? although it does have a forge version link

anybody know how to help? is there a way to search the mods on aternos by curseforge link?

Thank you!

It is definitely a Fabric mod. That mod can only be available in the "Mods" section if you install Fabric software into your server.

but there is a forge version available on curseforge. I have it working fine in my modpack.

if there's no other solution, is there any way I can install both forge and fabric on the server so I can put this mod in?
