One of the simplest ways to hide a message involves utilizing uppercase letters.
Given a text, collect all uppercase letters into a single word, maintaining their order of appearance in the text. For instance: 
text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec odio. Praesent libero.'
By gathering all the uppercase letters, the hidden message becomes "LIP".
