Error in apt update on Debian 12 - Raspberry Pi 5

Hi,

I am running a few RPI5 with Debian 12 using Zymkey 4. Recently, when I run apt update, I get an error from zk-sw-repo.s3.amazonaws.com/apt-repo-bookworm-aarch64. It says “The following signatures are invalid: EXPKEYSIG scott@zymbit.com

How do I correct this?

Thank you
