How to "force" multiline text in a toast message

[il77781]

Hello.
How can I make the toast message text "forcefully" wrap to the next line?
Unfortunately, using \n and <br> does not work...

type: custom:button-card
name: Card for toast
tap_action:
  action: toast
  toast:
    message: Thirst line '\n' Second line

This is not supported by Home Assistant (button-card just calls Home Assistant to display the toast messages). It is single line only.

I got it, thank you!
Although, if the toast message is very long, it somehow splits into several lines on its own...
