Bluetooth phone audio routing to phone

On the Android devices that I connect the laptop I usually have the option to enable “phone audio” routing option in Bluetooth.

However, in the FP3 I can only enable media audio when the devices are paired. There is no toggle to enable this and phone audio output is neither routed to the laptop nor is laptop audio routed to the phone.

Basically I want to use the phone as a “gateway” connected via Bluetooth to the laptop, so I can phone with the laptop.
