Hello! I'd like to request a mod to be added. On the suggestion area for mods/plugins when I enter the official CurseForge link to the mod, it says the mod is client-side, not server side, so the mod cannot be requested to be added, but even though I have the mod installed client-side none of the features are available. (BackSlot, the mod that this is an addon to, is already on Aternos, but the official addon to it isn't)
Here's the link to the mod: https://www.curseforge.com/minecraft/mc-mods/backslotaddon
As of writing this, it has 710,766 downloads and the first version was released on October 7th, 2020, so it shouldn't be too new.
Thank you, -Zingy
