We have created a modern communication site and the goal is to list all document libraries within that site on the homepage in alphabetical order, dynamically i.e so that when a new library is created it is shown.
I have seen the following article: https://sharepoint.stackexchange.com/questions/292959/how-to-sort-by-name-with-the-highlighted-content-web-part however the RefinableString isn't populating after a full crawl.

We would prefer not to nest all document libraries within another and was therefore wondering if anyone has any suggestions to achieve the required goal?
