Can anyone provide me guidance on this request?

I want to use the Windows 11 "Your Phone" function, which links the user's PC and mobile phone via a shared Wifi connection.

Is there a device I can purchase that creates a Wifi connection that the "Your Phone" app can use, but that does not require an additional connection to an outside internet service?

In other words, I am looking to create this network: <PC - Wifi device - phone>

I don't want to have to add the outside internet connection that would connect to the Wifi device.

Thanks!
