MX 23.4 xfce - battery lavel indicator for Bt headphones wanted

In the lower right corner of my screen, I can see the battery level of my laptop, but if I connect my BT headphones I don't know the according battery level until they stop working.
Is there any way to add that information right to where the ordinary battery level is being displayed or perhaps even add it to Conky, please?

Apparently we need to edit the configuration file
/etc/bluetooth/main.conf and change the line
to
save the file.
I'm running systemd with MX KDE, so I restarted bluetooth with
(try rebooting if this does not work), reconnected my device, and now its charge level shows in the little Bluetooth taskbar widget when I hover over it.
Let me know if this works on XFCE! You can see it also in the terminal now with the command:
Mine has the battery % on the last line:

Battery Percentage: 0x28 (40)
So Conky should be able to use that value with the right magic code to scrape the value.

Sorry, it doesn't seem to work.
I already tried that guide, which led me to my question here.
In the bluetoothctl info, I didn't find any line referring to the wanted battery percentage value,
but I will try it once more, to be sure I didn't miss anything on my first attempt (now, after your post, I actually know what to look for).
I will report back afterwards, asap ...

I have heard that some headphones use a nonstandard method to communicate, but I'm using some cheapo BT earbuds. I also have some other cheapos, like several sets of headbands/sleep masks with headphones built in, that one can pick up for a few bucks on AliExpress...yeah, this one works too:

**edit***
ah, the usually battery monitor in KDE picks it up right off, if you left click to bring out the expanded battery info. Haven't tried Xfce yet, but even if it doesn't, you could probably make a genmon plugin with a custom bluetoothctl info command work to display a percentage.

Does it show up on the xfce taskbar BT widget like the Plasma one if you hover the cursor over it?

it shows in the Xfce power manager when you left click to get the expanded battery info, just like in KDE.
so easy peasy really.

Not hovering on the panel widget. If you open Bluetooth Devices and hover over the symbols to the right of a connected device it does show up.
I'm not convinced it's always a real reading since it doesn't seem to change. It was 90 just after removing from the charger, and is still at 90 after listening for half an hour. Of course this is an $8 set of headphones from Ollie's Outlet.

Works perfectly on Xfce, no restart needed, just stopped and restarted BT service. This is with my lower mid range Sennheiser HD540 BT Headset (all I could afford) which I use to fix up bad voice recordings.
Blueman Battery icon now shows when connected
Right click and select info in blueman does not show battery info.
Xfce Tray Power Icon shows it
