Hello, Aternos Team. Can you please add mod "Sculk Sensor"?
https://www.curseforge.com/minecraft/mc-mods/sculk-sensor
This mod adds the Sculk Sensor block from the future version of Minecraft 1.17. This block responds to sounds, and gives a Redstone signal if a sound like footsteps or removing the block appears next to it.
Thank You.
