Show notifications for reactions to your messages

### Your use case

#### What would you like to do?

See a notification when someone reacts to my message.

#### Why would you like to do it?

Signal has this, and its very useful. I often like to know immediately if someone has reacted to my message, thumbs upping it, etc.

#### How would you like to achieve it?

Have it either as a setting, preferably on by default since signal has this.
