DataWeave programming challenge #5: Reverse a phrase's words, but keep the punctuation

In this post:
This challenge is based on Codeacademy's Reverse Words challenge
Try to solve this challenge on your own to maximize learning. We recommend you refer to the DataWeave documentation only. Try to avoid using Google or asking others so you can learn on your own and become a DataWeave expert!
Input
Consider the following input payload (can be of txt format):
Hello world
May the Fourth be with you
Hello world!
With you, be May the Fourth
With you, be May the Fourth!
Explanation of the problem
Create a DataWeave script that will reverse the order of each one of the words in a phrase to form a new phrase. Each phrase or sentence is separated by a new line. Each word is separated by a space. However, the punctuation signs (! and ,) will have to stay in the same place. Lower/upper cases can be kept as-is.
For example:
"Hello world!" becomes "world Hello!"
"With you, be May the Fourth!" becomes "Fourth the, May be you With!"
Expected output
In this case, the expected output would be:
[
"world Hello",
"you with be Fourth the May",
"world Hello!",
"Fourth the, May be you With",
"Fourth the, May be you With!"
]
ℹ️ Note: You can keep the output as a JSON or as a text, whatever your preference is.
Clues

Clue #1
Keep the index of each punctuation sign so you can insert it there later
Clue #2
You can use the isAlphanumeric function from the Strings module
Clue #3
You can use the scan function to separate each phrase in an Array of Strings
Clue #4
You can use the joinBy function to transform from Array to String
