Currently, to configure the notifications mute lists, users must go to Special:Preferences and add the username manually. A more standard user experience would be to add a way to mute the user by taking them to Special:Mute (added in T218265 and related tickets).
Echo already has an ellipsis menu that allows for advanced options:
|From any page||On Special:Notifications|
- For notifications that are triggered from one user to another (see list below) add an item to the ellipsis menu
- Icon F31722158
- Label: Mute notifications from USERNAME
- On click, it should take the user to Special:Mute for that username with the "Mute notifications for this user" checkbox pre-checked.
