Windows 11 has added hearing aid support using BLE 5.x
The early access preview has been made available in build KB5026446
I have ordered an Intel ax210 wireless card for my laptop rather than the USB dongle path (my wireless wifi/bt adapter is pcie based and is a small plugin card on motherboard, I am upgrading it for about $14, cheap enough) if you have a new laptop, it is likely that your wireless is an m.2/pcie based card, that’s how pc mfgs avoid costly fcc certification.
Here is a thread on hearing tracker that talks about MS BTLE audio support Windows 11 to add Bluetooth LE support for hearing aids
Here is Ms link to check HW modem BLE compatibility Check if your Windows 11 PC supports Bluetooth Low Energy Audio - Microsoft Support
Hope this helps.
