V4.1.7: how to do New lines in Welcome message in Strings.psd1?

Using 4.1.7 version and is there a way modify the custom message in the strings.psd1. is there a way we can create a new line. Like we need this to separate in to 3 different line simple line :

Application A will install automatically when the countdown ends.
The installation takes about 15 minutes and requires a reboot.

Please save your work and close all applications. Click Install Now to begin early'

Have you tried using `n or `r`n ?:
NOTE: These are BACK-TIC characters in front of the n.

Application A will install automatically when the countdown ends.`n
The installation takes about 15 minutes and requires a reboot.`n
`n
Please save your work and close all applications. Click Install Now to begin early

i get the following error
At line:243 char:6

  •          'nPlease save your work and close all applications. Clic ...
    
  •           ~~~~~~~
    

Unexpected token 'nPlease' in expression or statement.

At line:243 char:6

  •          'nPlease save your work and close all applications. Clic ...
    
  •           ~
    

The hash literal was incomplete.

Found that we need to use double quotes then it is working
CustomMessage = "The installation takes about 15 minutes and requires a reboot.nnPlease save your work and close all applications.`nClick Install Now to begin early."

Don't use the single quote character, use the the BACK-TIC character.
