Allbrightness spoon isn't working on BigSur (Intel)

I tried really hard to make the AllBrightness spoon works for my setup, but I couldn't 😞

I added the next lines into my init.lua file:

```
hs.loadSpoon("AllBrightness")
spoon.AllBrightness:start()
```

I also added the spoon into my local spoons folder.
To make sure the spoon was loaded, I modified the spoon to have custom logs about the captured events.

```
print(event['type'])
```
(at the start of the event function)

After reloading the config, the spoons was triggered for some SystemDefined events. The console showed perfectly SOUND_UP, SOUND_DOWN events (as a result of my custom logs). However, BRIGHTNESS_UP, BRIGHTNESS_DOWN were never printed, even when I changed the brightness using standard keystrokes. It is worth noting that nothing at all was printed when pressing on these keys.

Does anyone experience anything like that? Is it a change in OS BigSur? Is it just my Mac?

Thanks in advance 😄
