Just going to put my 2 cents in:
I have Oticon Intent HAs that support Bluetooth LE. (They also came with the ConnectClip bridge device)
If I attempt to pair them on a Lenovo Yoga Gen 7 with Windows 11 23H2 they show up when doing a Bluetooth discovery and the icon is a Hearing Aid icon. When I click on the first one it even tells me it found the other one and asks if I want to connect it too:
Once I click Connect it appears to connect and then the device screen shows the status under the hearing aid change to disconnected and it won't connect again. They show up in the Device Manager under Bluetooth along with a dozen instances of "Bluetooth LE Generic Attribute Service".
It looks like Windows 11 24H2 is coming with some Bluetooth updates so I'm hoping this will fix the issue.
In the mean time I can continue to use the ConnectClip bridge device. It's not always the most reliable so most of the time I just use a headset and offset one side to sit on top of my ear over the Hearing Aid mic.
