Bose Quiet Comfort 35 Remaining Battery Reporting

[Hugues <morisset.hugues@gmail.com>]

Hello,

I own a Bose QC35 bluetooth headset, sound is working great with
pulseaudio, but the battery reporting does not, I believe it is a
bluetooth issue because the device info doesn't say anything about
battery or power.
Any idea how I can make it report the remaining battery to upower so it
appears in my DE ?

The device info from bluetoothctl
