Thank you email in service desk

Hi,

I’d like to add an unsubscribe link in the thank_you.md template

Do you know what tag should I use? I’ve tried many options but none of theme are working.

What I tried :

[Unsubscribe ](https://domain.com/-/sent_notifications/%{key}/unsubscribe)

[Unsubscribe ](https://domain.com/-/sent_notifications/%{ISSUE_PATH}/unsubscribe)

many thanks
