Only allow users to view sites they have access to

Hello all,

I'm a Sharepoint admin for my organization and my supervisor would like me to set up our Sharepoint to only show users team sites that they're already a member of. We have a hub site that lists all of our available team sites but I'm not sure if there's a web part or any way of setting up this configuration that doesn't require some kind of third party solution. Any help on this would be greatly appreciated.
