Sharing macro across multiple users/documents

[Mikey]

Setup: Multiple users need the ability to search hundreds of various documents for specific words/terms (at last count there were 22). They would need to open each document, do the search and get the results.



Solution: I created the macro to do the job within a test document.

Question: the macro needs to be run against the content in the other (hundreds) of docs. How do I get the macro into all of the other documents where it doesn't exist?

Systems are a mix of Win 10/11. Word versions are either 2019 or 365.

Thanks!
