Bluetoothctl does not display battery energy status

[mauricio.historia]

I enabled the bluez experimental flag and pointed out the kernel modules from the manual with the exception of 'Bluetooth High Speed ​​(HS) features" which I didn't find. I enabled the Experimental = true line in /etc/bluetooth/main.conf.

On the Debian system bluetoothctl info correctly displays "Battery Percentage" on the same headphones (Galaxy Buds Pro 2) on Gentoo it is not displayed.

Does anyone have any ideas?
Thanks.
