Filtering a Content Query Web Part using query string parameters in SharePoint Online (Modern Pages)

Hi DaveMehr365, thank you so much for your feedback.

Apologies as I failed to mention that we are using the React Content Query for modern pages, which we download a while ago, we are going to check again to see if there is a new version or ask for feedback there.

I do have a follow up question for you.  I like the approach of using search, but let's say you are building a site to manager your Vendors.  So you have a Vendors List, a Vendor Contacts List and a Vendors Document Library.  I can easily build a search page that will allow me to search and facets to filter the results, etc.  What if I wanted my users to click on a Vendor on the search results and take them to a Page that will display all the information of that vendor (vendor information, contacts and documents), how would you go about building this?  I tried building a page with 2 List Content Parts and a Document Library and connecting the parts via Dynamic Filtering, but I'm having a hard time to filter the Vendor List with one via Query String parameter.

Let me know your thoughts on this.  Thank you
