How difficult would be be to add a "react" button in the notification, with a set default emoji like the ❤?

Flow👇

*prerequisite: phone is locked, screen off

1) user comments on note

2) I turn on phone, see notification

3) I tap "react" directly inside notification, sends my set default emoji to react to said comment

4) return phone to locked mode, screen off
