How to create a linebreak in yarn dialogue using variables?

(Or other methods of creating a manual linebreak in yarn)

I see that Slash has posted a possible solution in this thread here:

However, I’m still not savvy on how exactly Gdevelop works, so I’m having difficulty understanding how to implement it. If anybody could explain in more detail, or better yet provide an example project for me, I’d be very grateful.

For more context, the reason I’d like to implement manual linebreaks is because the text scrolling in Gdevelop still types on the same line for a moment before correcting itself and moving the written word to a new line if there is not enough space for it. The jump does not look very good.
