Libre calc - insert line or paragraph break in text cell

I’d like to insert a line or paragraph break inside a cell that has text using regular expression (which I’m new to).

eg.
From:
Reference Lidia

To:
Reference
Lidia

I’ve tried the following (with regular expression box ticked), none have worked:

*Find: Reference

Replace: Reference \n*
and Replace: Reference \n\n

What am I missing?

It’s not possible by Find&Replace, see some topics like that:

LO documentation writes:

Using ‘\n’ in the ‘Replace with’ box will replace with the literal characters ‘\n’, not a hard line break.

Macro? - Or use a formula containing char(10) for linefeed, see above first link…
