Notification template username by user email

[AI-FL]

Is it possible to use a defined user's name in table by useremail. For example in the push notification body, I would like to use something like: "Joe updated the record" instead of "joe@email.com" updated the record. If I make a separate table that associates the useremail() with a user's name, can I use this in an expression in the notification body?

Could I use this with capturing the user who last updated the record?  How do grab that piece of data?

For example by inserting a record in another Log table at the time of the change.
