A template-related question came up: https://github.com/nf-core/mhcquant/pull/401#discussion_r2540984454 What is that HOOK_URL used for?

This is for the teams/slack hook to send a message when the pipeline succeeds/fails

It's how messages like this one shows up on slack: https://nfcore.slack.com/archives/C050H771L2H/p1747939133313119

Great, thanks!
