Filtering out onmicrosoft accounts in the react-directory webpart

[johnsoep]

I'm working on seeing if we can utilize the react-directory webpart for my organization. I work in at a State University and we have to migrate our campus directory solution to a new platform within a year. We're also working on implementing a new Intranet utilizing SharePoint so I am really pushing to get as much into our SharePoint environment as we can and I think that the react-directory webpart meets most of our needs.

The one adjustment that I need to make is to get the webpart to ignore the onmicrosoft accounts. We have our environment setup to work off our domain, but when I do a search in the react-directory webpart it is showing Microsoft Bookings and M365 local accounts. I would like to adjust the query to only return our domain.edu addresses but I'm not 100% sure where to put that. My TypeScript is pretty basic and I don't have a lot of programming experience in the SharePoint Web Part world. Any feedback or tips would be greatly appreciated!
